Firebase - iOS Swift: FIRAuth.auth().signOut() not signing out current user

Question

I\'m building an app using Firebase with an initial SignInViewController that loads a sign in page for users to authenticate with email which triggers the follo

Answer 1

I just had what I think is the same problem - Firebase + Swift 3 wouldn't trigger stateDidChangeListeners on logout, which left my app thinking the user was still logged in.

What ended up working for me was to save and reuse a single reference to the FIRAuth.auth() instance rather than calling FIRAuth.auth() each time.

Calling FIRAuth.auth()?.signOut() would not trigger stateDidChangeListeners that I had previously attached. But when I saved the variable and reused it in both methods, it worked as expected.
