Firebase UI - Apple Login issue #830
Description
I am facing an issue with the new Apple Login using Firebase Auth UI.
My setup:
Target OS: 12.0
Language: Swift
Device: iPhone 6S
OS: 13.3
Crash Frequency: Consistently reproduced
Pod Setup:
pod 'Firebase/Core'
pod 'FirebaseUI', '~> 8.4.0'
pod 'Firebase/Messaging'
pod 'Firebase/Analytics'
When trying to authenticate using Apple Login ONLY on iOS 13 and above, the app crashes with the following trace just after Apple Login is done through Touch ID. When I stepped through line by line in debug mode, the crash doesn't happen. I think there is some issue with accessToken getting cleared after Apple Login. Kindly look into the issue and provide the resolution.
Following the code for Auth UI.
private func getAuthUI()->FUIAuth?{
if let authUI = self.authUI{
return authUI
}
else{
if let auth_ui = FUIAuth(uiWith: auth){
auth_ui.delegate = self
var providers:[FUIAuthProvider]
if #available(iOS 13.0, *) {
auth_ui.isInteractiveDismissEnabled = false
providers = [FUIFacebookAuth(permissions: []), FUIGoogleAuth(), FUIOAuth.appleAuthProvider()]
} else {
providers = [FUIFacebookAuth(permissions: []), FUIGoogleAuth()]
}
auth_ui.providers = providers
self.authUI = auth_ui
}
return self.authUI
}
}
