cloudkit share data between userscloudkit share data between users

After the share is accepted, NSPersistentCloudKitContainer automatically syncs all of the shared objects into the local store. we can share the data our applications create. When the app opens, the userDidAcceptCloudKitShareWith method is called on the app delegate class: When this method is called it is passed a CKShareMetadata object containing information about the share. Using a single managed object context, my application can access data in both stores. Log in to your iCloud account on a real device. Next, we'll take a deep dive into the mechanics of sharing. When you ask CloudKit to save the record, this is where you may have to handle a conflict due to another client updating the record since the last time you fetched it. Apple has been adding data sharing into many of its first-party apps, including: Files Reminders Notes Calendar Photos Activities Find My Maps Music Health With NSPersistentCloudKitContainer, applications can operate on shared objects from any Apple device. It is capable of handling large file transfers seamlessly. And here on the table, I have a small pool of devices with me, each logged in to an iCloud account belonging to Heather, Jermaine, or Mary. Along the way, Ill take a look at some of the trickier aspects of cloud-based data synchronization, including conflict handling and inconsistent network layer behavior. Select recordName from the list and ensure the index type is Queryable. How can I change a sentence based upon input to a command? NSPersistentCloudKitContainer manages these zones. One user shows up as a Owner and the other as a Private User, with both users having Read-Write permissions. Here I used isShared to decide whether or not to convert the title of a post to an attributed string and prefix it with the person.circle symbol to show that the post is part of a share. Let's get started with sharing. Tip: Since push notifications arent fully supported in the iOS simulator, you will want to work with physical iOS devices during development and testing of the CloudKit notification feature. Now that you have the method to perform the share, you need to present the CloudSharingView when you tap the Share button. It has a wide variety of actions I can take, including a number of ways to share. Please enable JavaScript to enjoy the best experience. To get the most out of this session, check out our previous videos on NSPersistentCloudKitContainer: "Using Core Data With CloudKit" from WWDC19 and "Sync a Core Data store with the CloudKit public database" from WWDC20. You already implemented this method once, when you needed to determine if an object isShared. that he is a Read-Only participant on the share. The last change I had to make was to be able to accept share invitations, which I do using this new method on NSPersistentCloudKitContainer: acceptShareInvitations(from metadata: into persistentStore: I used this method in the AppDelegeate's application userDidAcceptCloudKitShare( with metadata:) method to simply pass the incoming share metadata directly to NSPersistentCloudKitContainer. An object that represents activity in a persistent CloudKit container. Once youre in this section, you need to specify the container you want to see. These days, modern mobile application development requires a well thought-out plan for keeping user data in sync across various devices. Then, I set its CloudKit container options databaseScope property to .shared. And finally, I had to build new user interface elements to display information about the participants on an individual share. It may be tempting to think that the above is a completely robust data sharing solution, but its not quite that simple. If you attempt to select record type as CD_Destination and query records from here, you receive an error stating Field recordName isnt marked queryable. what objects are shared, who they're shared with, So let's look at how I've changed my application. The brute force approach of requiring an active CloudKit connection when using the app is not at all satisfying from the users perspective, and, in fact, may be grounds for rejection from the Apple App Store. NSPersistentCloudKitContainer includes a number of API methods to align with each of these concerns. Last, open HomeView.swift and look for the swipeActions modifier. Its fair to say iCloud got off to a bit of a rocky start. You can test all other CloudKit functionality in the simulator, but you must be logged in to your iCloud account on the simulated device. Tap the shared object to go to the detail screen. Due to network latency, airplane mode, and such, CloudKit will internally handle retries and such for operations at a qualityOfService of utility or lower. where my friends and I can share our photos with each other. Under the Schema section, select Indexes. New in iOS 15 is acceptShareInvitations(from:into:completion:). What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? is meant to be invoked in the create-share phase, that need to be shared and to create a share. Asking for help, clarification, or responding to other answers. However, such conflicts can arise from other circumstances. These values are decrypted locally on device after they're downloaded from the CloudKit server, and they're encrypted locally on device before they are uploaded to the CloudKit server. directly to NSPersistentCloudKitContainer. To begin the sharing process, add the following code to your persistentContainer below the // TODO: 1 comment: This code configures the shared database to store records shared with you. I set the BlockBasedProvider as the provider. Tapping this button removes a destination from your travel journal. Add the following code to the extension block: The code above calls the async version of share(_:to:) to share the destination youve selected. Its intended for experienced iOS developers who are already familiar with Apples frameworks and with Swift. I adopted a new method on NSPersistentCloudKitContainer to create the share. So how does NSPersistentCloudKitContainer know where to keep your records? The most amazing part is that because your data is now synced in iCloud, you can run your app on a completely different device thats signed in to the same iCloud account and see all your data! If a match returns, this object is already shared. Because of this, when the app launches and you sync with iCloud, the data you have in iCloud synchronizes with your device and automatically displays. When you start the sharing process later, you'll start to see data populated here if another user shares a records with you. Select Private Database. Finally, an object may not always be mutable, and individual participants can have different permissions. Instead of invoking methods on NSPersistentCloudKitContainer. Stay active, close your rings, and have a great WWDC 2021. In my example, I do this by using CKFetchRecordZoneChangesOperation and CKServerChangeTokens. I'll tap the Action button to bring up the sharing controller, but this time, I want the share to be read-only so that the participants can't edit or modify the contents of the share. [music]. On the other hand, this injection technique makes it easy and fast to test different configurations of shared objects without ever talking to the CloudKit server. It rejects specific requests with enough error context in the response to allow each client to make a local, enlightened decision about how to resolve the conflict. Now, encryption with CloudKit is an at-introduction time decision. To change the permissions and access to this data, Apple has done all the heavy lifting for you. I want to send each person an invite to work on this post with me via email. Pauls been a developer for nearly three decades, working with many tech stacks but with a focus on Apple. Synchronizing a Local Store to the Cloud. Back in CoreDataStack.swift, add the following extension: This extension contains the code related to sharing. Manage Settings Once you add a destination, youll see it on the main screen like below. in a way that facilitates this type of injection. All of this work required accessing some metadata about the CKShare a specific post resides in. Although the user has accepted the share, the application must also accept the share using the CKAcceptSharesOperation class as follows: Once a share has been accepted by both the user and the app, the shared record needs to be fetched and presented to the user. to combine the .private and .shared databases. before they are uploaded to the CloudKit server. Third, create an iCloud container that hosts your data in iCloud. The same note fields for text and modified datetime can be stored locally in a file via NSKeyedArchiver or the like, and the UI can provide near full functionality based on this local copy. The way to enable these silent notifications is to set the shouldSendContentAvailable property on the CKNotificationInfo instance, while leaving all of the traditional notification settings (shouldBadge, soundName, and so on) unset. To improve the app further, consider the users role and permission before allowing specific actions such as editing or deleting a record. Once you add the destination, tap the destination to view DestinationDetailView. How might I do that? NSPersistentCloudKitContainer turns those managed objects into instances of CKRecord that are stored in CloudKit. directly to specific call sites in my application. There's a lot of new API to learn about. I might need to know whether or not an object is shared. CloudKit prefixes your entities with CD to distinguish them from traditional CloudKit records. Connect and share knowledge within a single location that is structured and easy to search. Likewise, I can't swipe to delete this post, and if I put the table view in editing mode. Checks whether the object is shared. with the CloudKit server in the container associated. I had to build new user interface elements, to display information about the participants, All of this work required accessing some metadata. provided by NSPersistentCloudKitContainer. In this example, theres just the one record, but for future expandability, this is a great potential performance benefit. CloudKit operations provide superior control over the details of how CloudKit does its work and, perhaps more importantly, really force the developer to think carefully about network behaviors central to everything CloudKit does. Did you figure it out? Here, youll add the code to accept the share. Generally speaking, youll be working with an NSManagedObject from your view. For iOS and macOS, Apple provides a robust toolkit, called CloudKit API, which allows developers targeting Apple platforms to solve this synchronization problem. CloudKit is built on top of Apples iCloud service. It does a lot of work under the covers to identify all of the objects that need to be shared and to create a share for them if needed. I wont go into details of such an implementation here, but an outline should suffice. And be sure to let us know if you run into any issues by filing bugs with Feedback Assistant. If I tap on it, I can also see the participants displayed at the bottom of the detail view controller with their role, permissions, and acceptance state. If you sent the invitation from a real device, that can be a simulator. With the introduction of CloudKit sharing it is now possible for individual app users to share private database records with other users. Save the changes. CloudKit provides much more functionality on top of this, especially for sophisticated data models, public sharing, advanced user notification features, and more. Go to the first device you created the share from, because you need to be the Owner to access the Share Options. depending on whether or not they are the owner of those zones. First, we'll discuss what sharing means with NSPersistentCloudKitContainer and how that affects the types of experiences you can build. A record? This is your Destination entity in Core Data. Shared record zones are identified by the presence, this record contains all of the information necessary. if I change this line of code to use an existing share, NSPersistentCloudKitContainer will attempt to assign. When storing data via CloudKit, CloudKit Console allows you to interact with the data in question and perform several other functions such as viewing logs. NSPersistentCloudKitContainer manages these zones and automatically assigns records to them. I simply give the new album a title and then tap Next to choose the set of participants. to store the objects an application creates. A user of an app could, for example, make one or more records accessible to other users so that they can view and, optionally, modify the record. CloudKit sharing involves the creation of CKShare objects initialized with the record to be shared. Add the following modifier to the Button: With this code in place, only users with the proper permissions can perform actions like editing or deleting. As you prepare to present your CloudSharingView, you need this property because the second parameter of CloudSharingView is a CKContainer. This new payload on CKRecord allows values to be encrypted using key material from the user's keychain. and how that affects the types of experiences you can build. a specific method for each customization I needed. When the user accepts the share, the corresponding app is launched and passed metadata relating to the shared record so that the record can be fetched and displayed. Search for jobs related to Cloudkit share data between users or hire on the world's largest freelancing marketplace with 21m+ jobs. This chapter has covered the basics of CloudKit sharing, a topic which will be covered further in a later chapter entitled An iOS CloudKit Sharing Example. Let's look at that change in a bit more detail. Build apps that share data through CloudKit and Core Data. was to be able to accept share invitations. bookmark, personalise your learner profile and more! For our purposes, a single view application containing a UITextView with the ViewController as its delegate will suffice. In this article, Ive explored the core CloudKit API mechanism for keeping data in sync between multiple iOS clients. Photos implements a system control here in the lower left that allows me to call up an Action sheet. From here, tap the Share button in the top-right corner. to NSPersistentCloudKitContainer to support sharing. An example of data being processed may be a unique identifier stored in a cookie. Photos also allows me to view the participants on the album. The SharingProvider protocol makes it easy. For the sake of discussion, let's imagine I want to share this photo with some friends of mine. Jordan's line about intimate parties in The Great Gatsby? These silent pushes happen entirely without user visibility or interaction, and as a result, dont require the user to enable push notification for your app, saving you many potential user-experience headaches as an app developer. This snippet of code is part of a test case I wrote, to ensure that its table cells correctly indicate. When a notification comes in that a record has changed, CloudKitNoteDatabase will do the heavy lifting of fetching the changes from CloudKit. But our applications are usually designed, NSPersistentCloudKitContainer has to also help us make sense, of all of these objects so that we can build. about the CKShare a specific post resides in. To learn more, see our tips on writing great answers. But let's take a look at how NSPersistentCloudKitContainer uses Record Zone Sharing to share managed objects. It checks databaseScope and determines whether its private or shared. It is important to be aware that when a share recipient accepts a share they are actually receiving a reference to the original record in the owners private database. The largest and most up-to-date collection of courses and books on iOS, However, you can get more functionality if you use a custom zone, most notably, support for fetching incremental record changes. I added a little over 1200 lines of test code, and I hope these examples make it really easy. to communicate these states and privileges. If you've worked with sharing before, you're probably familiar with hierarchical sharing, where these records are associated with a root record called the share. to call the contains method of the set I created. to display more information in my user interface. Here I've chosen four friends to share the photo with. But first, a quick discussion of CloudKit Errors. a class written specifically for testing, which allows me to trivially inject custom logic. This doesn't seem to work. This logic first checks to see whether the object is shared. That method works for documents saved to the current iCloud account. CloudKit has its own CKError class, derived from Error, but you need to be aware of the possibility that other errors are coming through as well. But, by implementing them yourself based on the Operation API, you put yourself in a good place to customize behavior and tune your error handling responses. It: Now, open DestinationDetailView.swift. Specify record type as CD_Destination. we think of our objects in terms of NSManagedObject. Participants can have different roles and permissions that constrain how they can act on a particular set of objects, which brings us to the second key concept: how NSPersistentCloudKitContainer and CloudKit structure these shared objects. In many cases, it can infer where records belong based on the relationship they have to other objects. However, CloudKit gives you the tools you need for this. Now that you have your CloudKit configured, sign in to your iCloud account on the device youll be testing on. the participants, and their permissions and roles. Look at the share options. I left off the scaffolding for creating the sample data, but the test crafts a mixed set of managed objects that it identifies as shared or not shared by the presence of their objectID in this set. What is the easiest way to share files between users with CloudKit? On Mary's device, I'll open Mail and tap the link inside the email I sent, which opens up my application. There you go! Owners create and share objects with a set of participants. If theres no error, the title of the share is set. Download iOS 15.0+ iPadOS 15.0+ Xcode 13.4+ watchOS 8.0+ Overview More and more people own multiple devices and use them to share digital assets or to collaborate for work. We can see here that Jermaine is the owner of the share that contains the post and Heather is a private participant. Tapping that brings up the set of participants. Here I'm setting the isSharedBlock to call the contains method of the set I created. Because there's no root record, NSPersistentCloudKitContainer also has to understand how the concepts of owners and participants apply to the entire record zone. where I needed to know whether or not an object is shared. When the dialog asks whether you would like to open the invitation, choose Open. To achieve this, iOS 15 introduces share(_:to:). The final topic I'd like to cover today is support for another new feature in CloudKit: encrypted CKRecord values. Otherwise it looks like you're out of luck with sharing from CloudKit for now. Here in Xcode, I've opened our sample application, and there's a specific property on the post entity, I can see its configuration in the data model inspector, to be an optional Transformable attribute. Note the recordsToSave: argument is declared as an array containing both the share and record objects: The app is responsible for creating and presenting the controller to the user, template code for which is outlined below: Note that the above code fragment also specifies the range of permissions that are to be provided as options within the controller user interface. The consent submitted will only be used for data processing originating from this website. The owner is the iCloud account that actually owns an object. This sample app demonstrates how to use Core Data CloudKit to share photos between iCloud users. For each participant, NSPersistentCloudKitContainer manages objects in two CloudKit databases, the .private and the .shared database. From this screen, you can take a few actions. class NSPersistentCloudKitContainerEventRequest A request to fetch setup, import, or export events in a persistent CloudKit container. Amazing! Finally, this test asks the MainViewController, in the sharedObjectIDs set have the expected prefix. Once the CloudKit schema is pushed to production, we can't change any of the field types. Sharing is by far the most complicated feature we have built in to NSPersistentCloudKitContainer. Look for the ToolBarItem that contains the Text("Edit") button. that controls who can access these zones that I own. This is a cute trick in Swift that allows me to simply check if the provided objectID is in sharedObjectIDs. These are all the changes I had to make for my first demo, but my application also needs to effectively communicate what objects are shared, who they're shared with, and what those participants can do. Finally, I'll tap Send to send the email. by tapping this person icon in the upper right. if the provided objectID is in sharedObjectIDs. Sync user data between multiple apps from the same developer. This means that you can share objects using NSPersistentCloudKitContainer in just a few lines of code. CloudKit sharing provides a way for records contained within a private database to be shared with other app users, entirely at the discretion of the owner of that database. If you have any questions or comments, please join the forum discussion below. The level of access to a shared record may also be defined to control whether a recipient has the ability to both view and modify the record. Our example use case is a simple note application with just a single note, for illustration purposes. The app designer is always in the best position to define rules for these situations, which can include everything from context-aware automatic merging to user-directed resolution instructions. Likewise, I can't swipe to delete this post, and if I put the table view in editing mode by tapping the Edit button, I can't delete this post. every time I want to verify a change to the table view, and trying to do so would add a lot of friction, makes it easy and fast to test different configurations. The first is the notion of a set of actors. CloudKit automatically configures every CloudKit-enabled app out of the box to have a public CKDatabase (all users of the app can see everything) and a private CKDatabase (each user sees only their own data). Swift, Android, Kotlin, Flutter, Dart, Server-Side Swift, Unity, and more! Then, open the starter project. This is a thorny problem with many gotchas and pitfalls, but users expect the feature and expect it to work well. Tapping that brings up the set of participants. Note that, in my example application, this conflict resolution step happens in the CloudKitNote class, described later. Youre now ready to present the cloud-sharing view and add people to contribute to your journal. The first step is to create a method that prepares your shared data. The simple act of writing a record to the database is straightforward enough, but in my example, with multiple clients, this is where youll face the potential issue of handling a conflict when multiple clients attempt to write to the server concurrently. To edit or update the caption or description, tap the destination cell to see the detail screen. Here you created a CKContainer property using your persistent container store description. Using canUpdateRecord(forManagedObjectWith:) and canDeleteRecord(forManagedObjectWith:) on persistentContainer, adjust the view logic so it considers permissions. The only way to distinguish the private records versus shared records is to tap the detail and view the role in the participants list. That means we can't change our mind later and choose to encrypt fields that aren't already encrypted today in production. Toptal handpicks top iOS developers to suit yourneeds. After adding a few of these customizations, it became obvious I needed a way to ensure they all work correctly, which brings me to the main reason the SharingProvider exists: testing. enum NSPersistentCloudKitContainer.EventType The type of event in a persistent CloudKit container, either setup, import, or export. To understand these challenges a bit more clearly, we need to identify two crucial concepts for sharing. This framework ( https://github.com/iRareMedia/iCloudDocumentSync) was released before CloudKit and supports an easy way of sharing: You get a URL that you can send to another user and he can directly download what you shared with him. CloudKit app require a few items to be enabled on the Capabilities Pane of the Xcode Target: iCloud (naturally), including the CloudKit checkbox, Push Notifications, and Background Modes (specifically, remote notifications). To improve this, go back to HomeView.swift. Thankfully, CloudKit is explicitly designed to handle this condition. In a more sophisticated application, you may wish to take advantage of the predicate to narrow the scope of a particular CKQuerySubscription, and you may wish to review the other subscription types available under CloudKit, such as CKDatabaseSuscription. Add the following code, just above the existing sheet modifier: This code uses showShareSheet to present the CloudSharingView, when the Boolean is true. I'll open the CoreDataCloudKitDemo managed object model, and there's a specific property on the post entity I want to show you called location. Why was the nose gear of Concorde located so far aft? [/spoiler]. Select your desired delivery method and send the invitation. I and, if allowed, other participants can add. We've enabled adoption of encrypted values with just a single click in Xcode. Theres just one catch: This controller is a UIKit controller, and your app is SwiftUI. Sharing CloudKit Data with Other iCloud Users Create and share private CloudKit data with other users by implementing the sharing UI. Build and run again. The code above stores a reference to each store when its loaded. Otherwise, use fetchShares(matching:) to see if you have objects matching the objectID in question. First off, you need to make sure youre starting from a valid CKRecord. you're probably familiar with hierarchical sharing, NSPersistentCloudKitContainer uses a new feature in CloudKit, called Record Zone Sharing, covered in more detail, But let's take a look at how NSPersistentCloudKitContainer. But ideally, we would have a single place directly in the Photos app where my friends and I can share our photos with each other. Modern mobile application development requires a well thought-out plan for keeping user data in sync across various devices. Now, I could go through this implementation line by line, but that's not what's important here. Enter a topic above and jump straight to the good stuff. This involves the creation of a CKFetchRecordsOperation object using the record ID contained within the CKShareMetadata object. Note that the same code will work for macOS clients as well, with slight adjustments for differences in how notifications work on that platform.
