iCloud synchronization on tvOS

问题

has anybody managed to get iCloud working on tvOS so far?

I am using key-value-storage and it successfully saves everything in iCloud. However, it does not synchronize the data between the iOS-App and the tvOS-App. I am using the same bundle-identifier for both apps.

Has anyone experienced the same issue?

So, it appears that Apple may have an issue here on the tvOS side, because if I follow Apple's instructions on Configuring Common Key-Value Storage for Multiple Apps I can share between and iOS App and a macOS App, but not the tvOS app using exactly the same setup.

Below are my results:

Apple's Instuctions that I used 1st:

So, CloudKit is all about the default Container rather than the App bundle ID directly. So, I setup my Primary iOS app with default container that will become the key-value share container.

Here is my Primary Entitlements file: I then stored two NSUbiquitousKeyValueStore pairs in the default store and retrieved the values:

    NSUbiquitousKeyValueStore.defaultStore().dictionaryRepresentation

So, in my macOS app I enable CloudKit as well, and remove the default container and set it to the Primary iOS apps container. Then in the Entitlements file I manually setup the com.apple.developer.ubiquity-kvstore-identifier to include the Primary App's bundle ID:

Uncheck default container and toggle Primaries:

Here is my Secondary macOS Entitlements file:

Then I run the macOS app and presto, I have the key-value pairs from the primaries default key-value store and retrieved the values easy-peasy:

    NSUbiquitousKeyValueStore.defaultStore().dictionaryRepresentation

If I then make the SAME EXACT MODIFICATIONS to my tvOS app, the defaultStore() show as empty and I cannot get it to share with the iOS and macOS app.

Here is my Secondary tsOS Entitlements file:

And no presto, no values:
