Sign in with Apple Plugin for Unity

This is a FREE, UNOFFICIAL, MIT licensed, open source plugin, to support Sign In With Apple in iOS, tvOS and macOS. The plugin is developed by the community, and it´s not the same one as the official plugin from Unity available in the Asset Store.

The main purpose for this plugin is to expose Apple's newest feature, Sign in with Apple, to the Unity game engine. The plugin started development as soon as Apple announced the feature and has been around for a while already. Version v1.2.0 was released recently, adding macOS support, that´s why I decided to also post it here as well.

On WWDC19, Apple announced Sign in with Apple, and on top of that, they announced that every iOS/tvOS/macOS Application that used any kind of Third party sign-ins (like Sign in with Facebook, or Sign in with Google), will have to support Sign in with Apple in order to get approved for the App Store, making it mandatory.⠀

The plugin is also available on GitHub:
