How to solve error in Swift cola using CocoaPods, Firebase?

Question

Swift

https://codepen.io/Swift_u/pen/GejoOe
Line "Auth.auth().createUser(withEmail: email, password: password, completion: { (user: User?, error ) in
if error != nil {
print (error!)
return
}
})"
Throws an error: "Cannot convert value of type '(User?, _) -> ()' to expected argument type 'AuthDataResultCallback?' (aka 'Optional<(Optional, Optional) -> ()>')"
tell me how to solve it. Ps. (user: User?, error ) changed to (user: Auth, error )

Answer 1

This may be because it is NOT necessary to define the types of input parameters if they are already defined in the createUser method itself . Moreover, you defined the types of these parameters incorrectly.

Auth.auth().createUser(withEmail: email, password: password) { authResult, error in
  // ...
}
