Using iOS Notifications, Cryptography and iCloud to build your own Chat App II
I should start this article with a disclaimer, it based on iOS 13, Swift 5 and Xcode 11.x. If you reading this and those numbers look dated, be forewarned.
I should also warn you that notifications and iCloud code, involve Apple’s infrastructure which means you will need an Apple Developers account to use them.
Finally Obviously this is part II, you need to go back to part I first, indeed you need to look at the notifications series before do that ideally.
