finishedWithAuth not called after authenticate method

Question

I have already set the clientID ,scope and then on button click in MyViewController ,i am calling method login from LoginCLass which works but after [signIn authenticate]

Answer 1

Since your LoginClass is a Swift class, the fix is to make it a subclass of NSObject.

I had the same issue: when I tried to set the delegate to a class that was not a subclass of NSObject, the assignment failed and the delegate remained nil. When I added NSObject as a superclass, the assignment worked as expected.
