ICLOUD KEY-VALUE STORE ACROSS APPS OUTSIDE THE STORE

Using iCloud Key-Value Store Across Apps We wanted to use this for a couple of our macOS apps that are not distributed through the App Store. The first thing that I noted was that in the documentation for NSUbiquitousKeyValueStore, the last paragraph of the Overview says: "To use this class, you must distribute your app through the App Store or Mac App Store" I was instantly discouraged by this and so I started looking at the other iCloud functionality to see if it had the same limits.
