I'm trying to add error handling in creating user button in iOS project using swift and firebase:
Here's the code for the button:
@IBAction func Register(sender: AnyObject) {
if NameTF.text == "" || EmailTF.text == "" || PasswordTF.text == "" || RePasswordTF == "" || PhoneTF.text == "" || CityTF.text == ""
{
let alert = UIAlertController(title: "?????", message:"??? ???? ???? ?? ?????? ????????", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "???", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
} else {
if PasswordTF.text != RePasswordTF.text {
let alert = UIAlertController(title: "?????", message:"????? ?????? ??? ?????????", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "???", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
} else {
FIRAuth.auth()?.createUserWithEmail(EmailTF.text!, password: PasswordTF.text!, completion: { user, error in
print(error)
if error != nil {
let errorCode = FIRAuthErrorNameKey
switch errorCode {
case "FIRAuthErrorCodeEmailAlreadyInUse":
let alert = UIAlertController(title: "?????", message:"??????? ??????", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "???", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
case "FIRAuthErrorCodeUserNotFound":
let alert = UIAlertController(title: "?????", message:"???????? ??? ?????", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "???", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
case "FIRAuthErrorCodeInvalidEmail":
let alert = UIAlertController(title: "?????", message:"??????? ??? ????", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "???", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
case "FIRAuthErrorCodeNetworkError":
let alert = UIAlertController(title: "?????", message:"??? ?? ??????? ?????????", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "???", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
default:
let alert = UIAlertController(title: "?????", message:"??? ??? ?????", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "???", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
}
} else {
FIRAuth.auth()?.signInWithEmail(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")
// self.performSegueWithIdentifier("SignUp", sender: nil)
}
})
} //else
})
} //Big else
} //Big Big else
}
}//end of
I'm not sure if the syntax of the errors in switch statement is correct or not!
Because when I tested it in the simulator it always gives me the defualt case which is unknown error!
+
I could not find the syntax in the documentation:
https://firebase.google.com/docs/auth/ios/errors
So, What's the correct syntax to add error handling using new firebase and swift!
