Try using a didSet on each of the AppStorage fields. This can either: immediately call updateAvailableWords whenever there's a change set a flag indicating that availableWords is out of date; make availableWords a computed property that updates itself only if that flag is true Also, I would make availableWords private(set) - external clients should not be manipulating it directly.

I know this is an old question, but you can test this kind of error-handling logic by temporarily adding code to throw these errors, e.g.: throw CKError(.requestRateLimited, [CKErrorRetryAfterKey: NSNumber(value: 10)

I was able to solve this using the StackOverflow question mentioned by @Claude31 below. In my case, I opened "Devices and Simulators", then unpaired the device, closed Xcode, opened Xcode, and re-paired the device.

This seems to be fixed in Beta 4
