Save User's name in Firebase - Swift - swift

Question

I have three text field in my registration form. The e-mail id and password of the user are used by the Firebase SignUp method to create a new user. But I also want to save the user's name according to what they input.
My current code is;
#IBAction func registerPressed(_ sender: Any) {
SVProgressHUD.show(withStatus: "Setting you up")
dismissUIElements(value: false)
let currentUserName = userName.text
if currentUserName?.isEmpty == false {
FIRAuth.auth()?.createUser(withEmail: emailTextField.text!, password: passwordTextField.text!, completion: { (user, error) in
if error != nil {
print(error!)
SVProgressHUD.dismiss()
self.dismissUIElements(value: true)
} else {
print("Registration Successful!")
SVProgressHUD.dismiss()
self.dismissUIElements(value: true)
self.performSegue(withIdentifier: "goToSelectionFromRegister", sender: self)
}
})
}
else {
SVProgressHUD.dismiss()
SVProgressHUD.showError(withStatus: "Please enter your name!")
SVProgressHUD.dismiss(withDelay: 1)
self.dismissUIElements(value: true)
}
}

Answer 1

You need a function that will register the user and then create the child for that user in Firebase.
let databaseRef=//your path to users.
func registerUser(userUsername userName:String, userEmail email:String, userPassword password: String, userCreationComplete: #escaping (_ status: Bool, _ error: Error?) -> ()) {
Auth.auth().createUser(withEmail: email, password: password) { (user, error) in
guard let user = user else {
userCreationComplete(false, error)
return
}
let userData = ["userName": userName.text] as [String : Any]
ref.child(user.uid).updateChildValues(userData)
userCreationComplete(true, nil)
}
}
Then you call the function from within registerPressed() and you pass it the textfield values but make sure that none of them is empty.

You will create a new data table that stores that info. It won't be done in the create user function.
// create a reference to the DB
ref = Database.database().reference(fromURL: "https://your-project-name.firebaseio.com/")
//variables to store data
var myID : String?
var myName : String?
var myNumber : String?
var myEmail : String?
// creating the save user function
func saveUser(_ completion: #escaping(_ error: Error?) -> Void) {
if PageDataSource.sharedInstance.crudIsAvailable == true {
let usersRef = ref.child("users")
let myUserRef = usersRef.child(id)
myUserRef.updateChildValues(["User ID": id,
"Name": myName,
"Email": myEmail,
"Phone": .myNumber], withCompletionBlock: { (error, ref) in
if error != nil {
completion(error!)
} else {
completion(nil)
}
})
} else {
completion(NSError(domain: "Unavailable", code: 0, userInfo: nil))
}
}
// call the method like this to perform the save
func storeUser(completion: #escaping(_ completed: Bool, _ error: NSError?)-> Void) {
if let user = Auth.auth().currentUser {
myID = user.uid
myName = user.displayName
myEmail = user.email
// etc.,
completion(true,nil)
} else {
completion(false,NSError(domain: "No Current User", code: 1, userInfo: nil))
}
}
