Also tried this In your xcode, Go to PODS folder : Target Support Files => Pods-{Your Project} => Pods-{Your Project}-frameworks Change source="$(readlink "${source}")" this : source="$(readlink -f "${source}")" but it didn't worked

After months struggling with this issue, I finally worked it out, thanks to this https://curity.io/resources/learn/swift-ios-appauth/#get-the-code (thanks for that great example) which shows how to get OIDErrorCode.userCanceledAuthorizationFlow when user clicks on "cancel" I also subscribed to a notification in my controller : UIApplication.didBecomeActiveNotification and call my login function from the callback, when i'm sure the app is loaded as it should Hope it can help :)
