Converting to Swift 3 (Swift and Firebase Project)

问题

I have just updated my Xcode to Xcode8 and I have converted the project to swift 3.

In signIn function here:

  Firth. Auth()?.signIn(withEmail: self.EmailTF.text!, password: self.PasswordTF.text!, completion: { (user: FIRUser?, error: NSError?) in
                        if let error = error {
                            print(error.localizedDescription)
                        } else {

                           self.ref.child("UserProfile").child(user!.uid).setValue([
                                "email": self.EmailTF.text!,
                                "name" : self.NameTF.text!,
                                "phone": self.PhoneTF.text!,
                                "city" : self.CityTF.text!,
                                ])
                            print("Sucess")

                        }
                    })

I'm getting this error:

cannot convert value of type '(FIRUser?, NSError?) -> ()' to expected argument type 'FIRAuthResultCallback?'

What's the replacement of it in swift 3?

回答1:

Just replace it with :-

 FIRAuth.auth()?.signIn(withEmail:self.EmailTF.text!, password: self.PasswordTF.text!, completion: { (user, err) in
       if let error = err {
                        print(error.localizedDescription)
                    } else {

                       self.ref.child("UserProfile").child(user!.uid).setValue([
                            "email": self.EmailTF.text!,
                            "name" : self.NameTF.text!,
                            "phone": self.PhoneTF.text!,
                            "city" : self.CityTF.text!,
                            ])
                        print("Sucess")

                    }
    })
