Using iOS Notifications, Cryptography and iCloud to build your own Chat App.
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.

Finally I need say I already cover iOS notifications in another series, for which the I link in here. I’ll be using the code developed with it hence the mention.
