You can do the following...

let manager = LoginManager() // create object of LoginManager class
manager.logOut() //<- Logout if there is any existing session
manager.logIn(permissions: ["public_profile", "email"], from: self) { (result, error) in


   //your code goes here...

}

The FBLoginButton automatically starts the authentication session. Make sure you aren't calling FBSDKLoginKit.LoginManager().login() as a part of your button action. Instead, conform to LoginButtonDelegate to handle the result from the authentication session that results from the button tap.
