The unique record id name doesn't seem to be enough to find the record. The SharingProvider protocol makes it easy. Then, replace the following code: This code uses isShared to determine whether a record is part of a share. The version held by the server at the time you submitted the request. Due to network latency, airplane mode, and such, CloudKit will internally handle retries and such for operations at a qualityOfService of utility or lower. 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. First off, you need to make sure youre starting from a valid CKRecord. At the top level is CKContainer, which encapsulates a set of related CloudKit data. 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. Heres Apples sample project on Synchronizing a Local Store to the Cloud. 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. than the simple injection I used in the test. uses Record Zone Sharing to share managed objects. Checks whether the object is shared. Sync user data between multiple apps from the same developer. For iOS and macOS, Apple provides a robust toolkit, called CloudKit API, which allows developers targeting Apple platforms to solve this synchronization problem. that is allowed to operate on those objects in some way. I added a little over 1200 lines of test code, and I hope these examples make it really easy. In my .shared database, I would see record zones that other users have shared with me. If necessary, you then pass the updated server record to CloudKit to write the new record. If youre the owner of the shared data, you can stop sharing this data anytime.

From this screen, you can take a few actions. Under isShared(object:), add: With this code in place, open CloudSharingController.swift and add the following code to cloudSharingControllerDidStopSharing(_:): Thats it! 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. Both the CKShare and associated CKRecord object are then saved to the private database. directly to NSPersistentCloudKitContainer. Navigate to AppDelegate.swift and youll see SceneDelegate is empty. a specific method for each customization I needed. So that's how we use NSPersistentCloudKitContainer to combine the .private and .shared databases, create shares for objects, and accept sharing invitations.

In addition to this, you set databaseScope to .shared. To learn more, see our tips on writing great answers. Accepting share invitations and fetching the shared data. I'm Nick Gillett, an engineer here at Apple on the Core Data team. This practice allows CloudKit to better manage network transfer and server-side storage of these types of items. Synchronizing a Local Store to the Cloud. which tells it I'm ready to continue the sharing flow. Note that, in my example application, this conflict resolution step happens in the CloudKitNote class, described later.

For each participant, NSPersistentCloudKitContainer manages objects in two CloudKit databases, the .private and the .shared database. Our users need all of that information so that they can make good decisions about the objects they choose to share. In anticipation of this, split the save function into two steps. to write all of these tests and structure the application. If a match returns, this object is already shared. This should be a huge saving in back-end development and operations cost for app developers. Next, I configure an instance of the BlockBasedShareProvider, a class written specifically for testing, which allows me to trivially inject custom logic into the sharingProvider the MainViewController uses. And exactly how much did I have to change in the sample application? we can share the data our applications create.

It is important to be aware that this fetch operation must be executed on the shared cloud database instance of the app instead of the recipients private database. The first step is to implement the UIKit scene delegate method windowScene(_:userDidAcceptCloudKitShareWith:). However, to allow other users to interact with this data, you need to update your NSPersistentCloudKitContainer. Because there's no root record, NSPersistentCloudKitContainer also has to understand how the concepts of owners and participants apply to the entire record zone. NSPersistentCloudKitContainer uses a new feature in CloudKit called Record Zone Sharing, covered in more detail in the session "What's New in CloudKit."
