Firebase change photoURL - ios

Question

When a user taps their profile photo they have an option to select a new photo. I want to store the photo into my Storage and Database and update the view as soon as the imagePickerController is dismissed the new image shows on the screen, however nothing changes in the database and after logging in and out the old profile image is still there.
var user: User!
var dataBaseRef: DatabaseReference!{
return Database.database().reference()
}
var storageRef: StorageReference!{
return Storage.storage().reference()
}
func updatePhoto() {
let user = Auth.auth().currentUser
let newPhoto = profileImage.image
let imgData = UIImageJPEGRepresentation(newPhoto!, 0.7)!
let imagePath = "profileImage\(user.uid)/userPic.jpg"
let imageRef = storageRef.child(imagePath)
let metadata = StorageMetadata()
metadata.contentType = "image/jpeg"
imageRef.putData(imgData, metadata: metadata) { (metadata, error) in
if error == nil {
let changeRequest = Auth.auth().currentUser?.createProfileChangeRequest()
if let photoURL = metadata!.downloadURL(){
changeRequest?.photoURL = photoURL
}
changeRequest?.commitChanges(completion: { (error) in
if error == nil{
let user = Auth.auth().currentUser
let userInfo = ["firstLastName": self.nameOld, "email": self.emailString, "password": self.passwordOld, "location": self.locationOld, "interests": self.interestsOld, "biography": self.bioOld, "uid": self.uid, "photoURL": String(describing: user?.photoURL!)]
let userRef = self.dataBaseRef.child("users").child((user?.uid)!)
userRef.setValue(userInfo)
let credential = EmailAuthProvider.credential(withEmail: self.emailString, password: self.passwordOld)
user?.reauthenticate(with: credential) { error in
if let error = error {
print(error)
// An error happened.
} else {
print("AUTHENTICATED")
// User re-authenticated.
}
}
print("user info set")
}
})
}}}
func loadUserInfo(){
let userRef = dataBaseRef.child("users/\(Auth.auth().currentUser!.uid)")
userRef.observe(.value, with: { (snapshot) in
let user = Users(snapshot: snapshot)
if let username = user.firstLastName{
self.name.text = username
self.nameOld = username
}
if let userLocation = user.location{
self.location.text = userLocation
self.locationOld = userLocation
}
if let bio = user.biography{
self.biog.text = bio
self.bioOld = bio
}
if let interests = user.interests{
self.interests.text = interests
self.interestsOld = interests
}
if let imageOld = user.photoURL{
// let imageURL = user.photoURL!
self.storageR.reference(forURL: imageOld).getData(maxSize: 10 * 1024 * 1024, completion: { (imgData, error) in
if error == nil {
DispatchQueue.main.async {
if let data = imgData {
self.profileImage.image = UIImage(data: data)
}
}
}else {
print(error!.localizedDescription)
}
}
)}
}) { (error) in
print(error.localizedDescription)
}
}
override func viewDidLoad() {
super.viewDidLoad()
setGestureRecognizersToDismissKeyboard()
loadUserInfo()
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage{
self.profileImage.image = image
updatePhoto()
}
else if let image = info[UIImagePickerControllerEditedImage] as? UIImage {
self.profileImage.image = image
updatePhoto()
}
self.dismiss(animated: true, completion: nil)
}

From apple documentation, UIImagePickerControllerEditedImage: Specifies an image edited by the user and UIImagePickerControllerOriginalImage: Specifies the original, uncropped image selected by the user.
If the user does not edit the selected image, you should also call updatePhoto() function in order to upload the selected photo:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage{
self.profileImage.image = image
updatePhoto()
}
else if let image = info[UIImagePickerControllerEditedImage] as? UIImage {
self.profileImage.image = image
updatePhoto()
}
self.dismiss(animated: true, completion: nil)
}
