What's the problem with the code you shared? As in: what line in that code doesn't do what you expect it to do when you run it in a debugger? — Frank van Puffelen

It appears you're updating the email address to the same already existing email address. i.e. change (to: (auth.currentUser?.email)! to (to: (email)!. For an example, see my answer to this question. — Jay

To change the email address the user has to be logged in recently i would suggest doing this:

var credential: AuthCredential @IBAction func changeEmail() { if let user = Auth.auth().currentUser { // re authenticate the user user.reauthenticate(with: credential) { error in if let error = error { // An error happened. } else { // User re-authenticated. user.updateEmail(to: "email") { (error) in // email updated } } } } }

while credential is not initialed user.reauthenticate(with: credential) will crash.

This is effective method to solve it.

let user = Auth.auth().currentUser user?.updateEmail(to: "email") { error in if error != nil { // An error happened } else { // Email updated. } }
