Find centralized, trusted content and collaborate around the technologies you use most. If a match returns, this object is already shared. The final step is to set the cloudKitContainerOptions property for the sharedStoreDescription you created. NSPersistentCloudKitContainer automatically syncs. Learn iOS, Swift, Android, Kotlin, Flutter and Dart development and unlock our massive 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. At this point, if you shared the invitation via text message, open Messages and tap the invitation. The first is the notion of a set of actors. To complete the demo, I had to make two other changes. Careful error handling is absolutely essential for a CloudKit client. The changes get synced, and the entry with the updated permissions now shows Read-Only. Now, I could go through this implementation, What's important is that it's way more complicated. For these reasons, I am using the operations in these code examples. It's free to sign up and bid on jobs. When you create a destination, the data is being persisted via Core Data locally in your app. Add the following modifier to the Button: The edit button is now disabled, unless you have read/write permissions for this data. the participants, and their permissions and roles. directly to specific call sites in my application. based on the relationship they have to other objects. Every app automatically gets a default CKContainer, and a group of apps can share a custom CKContainer if permission settings allow. if the provided objectID is in sharedObjectIDs. Have a question? CloudKit sharing allows records stored within a private CloudKit database to be shared with other app users at the discretion of the record owner. As you prepare to present your CloudSharingView, you need this property because the second parameter of CloudSharingView is a CKContainer. Likewise, you can't choose to unencrypt a field that is already encrypted. Prior to the release of iOS 10, the only way to share CloudKit records between users was to store those records in a public database. Sharing CKAssets between users with CloudKit? If I tap on it, I can see that the Edit button is disabled and the participants entry for Jermaine shows that he is a Read-Only participant on the share. For example purposes, I included a basic sanity check to make sure I am updating the correct record, and then update the fields and notify the delegate that we have new data. NSPersistentCloudKitContainer turns those managed objects into instances of CKRecord that are stored in CloudKit. To improve this, go back to HomeView.swift. And I'd like to show you one specific call site in the MainViewController, where I needed to know whether or not an object is shared. In the window that comes up, enter your containers name. to combine the .private and .shared databases. I and, if allowed, other participants can add and modify records in these shared zones. Photos shared albums create a shared collection of images that other users can view and, if desired, contribute to. to store objects in a specific shared zone. Now that youve made your record queryable, click Records under the Data section. The CKFetchRecordsOperation operates on one or more records at a time. First off, you need to make sure youre starting from a valid CKRecord. Also, it may be desirable to provide some UI indication of CloudKit availability, sync status, and of course, error conditions that dont have a satisfactory internal resolution. For example, I can send it to my friends as an iMessage or email. 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. Amazing! Each participant will also have their own collection of devices. Within this handler, the CKShare object must be created and saved as outlined in the previous section. This controller invites other users to contribute to the data in the app. And finally, we'll briefly discuss how NSPersistentCloudKitContainer can help you enable some additional protection for sensitive data stored in iCloud. Within each CKContainer are multiple instances of CKDatabase. to NSPersistentCloudKitContainer to support sharing. Manage Settings The app can then take advantage of various OS-provided notifications, in particular, CKAccountChangedNotification, to know when a user has signed in or out, and initiate a synchronization step with CloudKit (including proper conflict resolution, of course) to push the local offline changes to the server, and vice versa. Then, I set the BlockBasedProvider as the provider for the view controller, completing the injection. Also, CloudKit provides a specific record type for large binary objects. Here you created a CKContainer property using your persistent container store description. Change the permission to View only. After adding a few of these customizations. Within this container, youre going to use the private database (because you want the users note to be seen only by that user) and within the private database, youre going to use a custom record zone, which enables notification of specific record changes. Last, if the current user of that share is the owner, returns. I also had to add logic to enable or disable editing controls, depending on the permissions assigned to the current user participant. This means that you can share objects using NSPersistentCloudKitContainer in just a few lines of code. A record? Each of these is mirrored to a persistent store in my application, one using the .private database scope and the other using the .shared database scope. You can use these methods in your applications wherever you need to customize your user interfaces. It is also possible to serialize CKRecords directly to and from local storage. that allows me to call up an Action sheet. 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. To dig deeper into CloudKit, I strongly recommend taking the time to view the various CloudKit presentations from each of the last few WWDCs and follow along with the examples they provide. For each participant, NSPersistentCloudKitContainer manages objects in two CloudKit databases, the .private and the .shared database. In many cases, it can infer where records belong based on the relationship they have to other objects. Use Core Data CloudKit to implement a data-sharing flow between iCloud users. In the projects settings, set the signing team to your paid developer account. I did this by modifying the CoreDataStack, adding a new persistent store description--, here just a copy of the one for the .private store, Then, I set its CloudKit container options, to be configured to mirror persistent stores, I adopted a new method on NSPersistentCloudKitContainer, share(_ managedObjects: to share: completion:). To achieve this, iOS 15 introduces share(_:to:). But in my application, I took a slightly different approach. For example, if you want to extend this app to handle multiple Notes rather than just one, you could do so more readily (and with higher resulting performance) than if youd just used Apples convenience APIs. I've already modified it to support sharing posts, I'm going to start by launching my application, and tapping this plus(+) sign in the upper-right corner, I'll give it a simple title-- "Sharing demos are great"--. This snippet of code is part of a test case I wrote, to ensure that its table cells correctly indicate. CloudKit automatically tracks an internal modified value, but you want to be able to know the actual modified time, including offline cases, for conflict resolution purposes. But let's take a look at how NSPersistentCloudKitContainer uses Record Zone Sharing to share managed objects. Were you able to figure it out? which tells it I'm ready to continue the sharing flow. Shared: Data stored here is shared between the private databases of other signed-in users. by the presence of their objectID in this set. Since CloudKit is deeply tied to Apples operating systems and devices, its not suitable for applications that require a broader range of device support, such as Android or Windows clients. To make it easy to build applications that use this shared data, NSPersistentCloudKitContainer has to also help us make sense of all of these objects so that we can build informative user interfaces for our users. In anticipation of this, split the save function into two steps. that aren't already encrypted today in production. This is a cute trick in Swift that allows me to simply check. and how to operate on records and objects. 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. Hi. Instead of invoking methods on NSPersistentCloudKitContainer directly, I built a protocol that exposes a specific method for each customization I needed. An example of data being processed may be a unique identifier stored in a cookie. But in my application, I took a slightly different approach. The class contains all the necessary methods and properties you need to interact with Core Data. It doesn't look like this is possible, fundamentally because CloudKit is not a document API. 2 Answers Sorted by: 8 In iOS 10 / macOS 10.12, it is now possible to share hierarchies of records in a user's private database with other users. where I needed to know whether or not an object is shared. But ideally, we would have a single place. Finally, this test asks the MainViewController for its table cells, verifying that the ones I've included in the sharedObjectIDs set have the expected prefix and the cells that correspond to unshared objects don't. When the user taps the link that was shared earlier and accepts the invitation, the delegate calls this method and launches the app. To achieve this, youll implement fetchShares(matching:). to display more information in my user interface. And now I can see the new post. Is something like this (or even better) available with the new CloudKit? before deploying your schema to production. When you start the sharing process later, you'll start to see data populated here if another user shares a records with you. Hiring? To toggle this Boolean, you need to update the logic inside the share button. It's free to sign up and bid on jobs. Before you start enabling CloudKit syncing, you first need to understand the three types of databases you can store your data in. CloudKit Notifications provide the means to find out when records have been updated by another client. but the resulting confidence and reliability are well worth it. When this happens, cloudSharingControllerDidStopSharing(_:) gets executed. that other users can view and, if desired, contribute to. Open CoreDataStack.swift. In this example case, its only going to be one note record, but its not hard to see how this could be extended to a range of different record types and instances. Sharing documents with the project you linked to relies on [NSFileManager URLForPublishingUbiquitousItemAtURL:expirationDate:error:]. Open CoreDataStack.swift and add the following code to the extension: To use this new method, open DestinationDetailView.swift. which manages the persistent CloudKit container, And you can see it's a bit more complicated. 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. Within a CKDatabase are CKRecordZones, and within zones CKRecords. I had to decorate the post table cells to indicate which ones are shared.
