What does User? has no member 'profileimageView' mean? - ios

Question

I am unable to understand what exactly the error is trying to tell me. I tried fixing it by using self and changing classes. Still will not help. Need a guide that could help understand what exactly I am missing or doing wrong.
import UIKit
import Foundation
import Firebase
extension LoginController: UIImagePickerControllerDelegate,UINavigationControllerDelegate{
func handleRegister(){
guard let email = emailTextField.text, let password = passwordTextField.text, let name = nameTextField.text
else {
print("This form is not valid")
return
}
Auth.auth().createUser(withEmail: email, password: password) { (self, error) in
if error != nil {
print(error!)
return
}
guard let uid = self?.uid else{
return
}
//sucessfully authenticated user
let storageRef = Storage.storage().reference()
// On the following line
if let uploadData = UIImagePNGRepresentation(self.profileImageView.image!) {
storageRef.putData(uploadData, metadata: nil, completion: { (metadata, error) in
if error != nil{
print(error)
return
}
})
}
let ref = Database.database().reference(fromURL: "https://bbooks-96cac.firebaseio.com/")
let userReference = ref.child("user").child(uid)
let values = ["name": name, "email": email]
userReference.updateChildValues(values, withCompletionBlock: {
(err, ref) in
if err != nil {
print(err)
return
}
// print("Saved user successfully into firebase DB")
})
}
dismiss(animated: true, completion: nil)
}
}

Answer 1

First, you are misusing the term self (I'm surprised there is no error here). You need a better variable name:
Auth.auth().createUser(withEmail: email, password: password) { (self, error) in
I would change self to user here and throughout what follows:
Auth.auth().createUser(withEmail: email, password: password) { (user, error) in
Second, user is then an Optional so you need to unwrap it:
if let uploadData = UIImagePNGRepresentation(user!.profileImageView.image!) {
