iCloud Key-Value-Store not working (Tried to access store that is unknown to the system)

I'm trying to use the NSUbiquitousKeyValueStore to store a value, but I am getting this error down below.

The local UserDefaults are working, but the iCloud Key-Value-Store isn't.

Is this perhaps related to the fact that I am using this configuration as a CloudKit container?
