I'm new to swift and Firebase, I'm trying to create an app with email login, I noticed that if the user didn't sign out before closing the application, the value FIRAuth.auth().currentUser.uid is seen as not nil in the second time to run the application
my questions: does the session expire in firebase? what is the duration? can we change it? how to change it and how to check if the session is expired?
Thanks for your help.
