Usage with Auth0

Auth0 has documentation regarding this specific feature, but here is a quick snippet for you to utilize in your applications. Keep in mind the specific parameters used are documented in Auth0's API explorer.

Prerequisites to using this library

The @invertase/react-native-apple-authentication library will not work if you do not ensure the following:

• You are using React Native version 0.60 or higher.

• (iOS only) You have setup react-native iOS development environment on your machine (Will only work on Mac). If not, please follow the official React Native documentation for getting started: React Native getting started documentation.

• (iOS only) You are using Xcode version 11 or higher. This will allow you to develop using iOS version 13 or higher, when the Sign In with Apple APIs first became available.

• Once you're sure you've met the above, please follow our Initial development environment setup guide.
