使用FIRAuth实施创建用户时遇到问题

Question

I've ran into this issue and have been trying to solve it for a few days now and it seems everything I try it creates more errors. I'm having problems creating a user with this function use FIRAuth and its telling me to add in a ; right before in, but it doesn't fix the problem.

Picture of Errors:

func handleRegistration() {
        guard let email = emailTextField.text, let password = passTextField.text
            else {
                print("Form is not Valid")
                return
        }



        FIRAuth.auth()?.createUser(withEmail: email, password: password, completion: FIRUser?, error) in

         if error != nil {
            print("Error")
            return
        }

        print("Login Successful")
    }

Try this :-

FIRAuth.auth()?.createUser(withEmail: email, password: password, completion: {(user, error) in

     if error != nil {
        print("Error")
        return
    }else{
        print("Login Successful")
        return 
   }
})
