Hi, got some more details from xcode
2020-04-04 17:02:26.514607+0100 HelloWorld[3422:896268] THREAD WARNING: [‘TouchID’] took ‘21.125977’ ms. Plugin should use a background thread.
2020-04-04 17:02:26.529443+0100 HelloWorld[3422:896522] [access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app’s Info.plist must contain an NSFaceIDUsageDescription key with a string value explaining to the user how the app uses this data.
However
ionic cordova plugin add https://github.com/simon-ntitle/cordova-plugin-keychain-touch-id.git --variable FACEID_USAGE_DESCRIPTION="For easy authentication"
so not sure why it is complaining
