The first is the notion of a set of actors. Here I'm setting the isSharedBlock to call the contains method of the set I created. Saving records is, perhaps, the most complicated operation. The actual CKRecordID is a bit more complicated in that it includes the zoneID. In addition to sending a share link, the app must also be adapted to accept a share and fetch the record for the shared cloud database. If it is, then this object is already shared. Customizations like this necessarily require more complicated code than if I chose not to support sharing. 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. In this simple Note application, with a single user switching between devices, youre not likely to see too many conflicts in a live concurrency sense.

Next, I configure an instance of the BlockBasedShareProvider. Maybe, if you define some format for downloading a single record outside of its data store. Ill focus on an iOS application, but the same approach can be used for macOS clients as well. At the top level is CKContainer, which encapsulates a set of related CloudKit data. CloudKit provides much more functionality on top of this, especially for sophisticated data models, public sharing, advanced user notification features, and more. I am not going to get very fancy in my example; I am using the modified field to declare that the most recent update wins. 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. How might I do that? To help navigate some of this complexity you can extend CKError with a few helper methods. Careful error handling is absolutely essential for a CloudKit client. But how does all of this work? The SharingProvider protocol makes it easy to test these decision points by injection. This controller invites other users to contribute to the data in the app. The final step is to set the cloudKitContainerOptions property for the sharedStoreDescription you created.
