Answer 1

You need to store the profile Image on the firebase storage,
after that imageURL will be retrieved. After the imageURL is retrieved you need to save it on the firebase database as a child of the userId.
Refer the code below
func handleRegister() {
guard let email = self.emailTextField.text, let password = self.passwordTextField.text, let name = self.nameTextField.text else {
print("Form is not valid")
return
}
Auth.auth().createUser(withEmail: email, password: password) { (user: User?, error) in
if error != nil {
print(error!)
return
}
guard let uid = user?.uid else {
return
}
//success
let imageName = NSUUID().uuidString
let storageRef = Storage.storage().reference().child("\(imageName).png")
if let uploadData = UIImageJPEGRepresentation(self.profileImageView.image!, 0.1) {
storageRef.putData(uploadData, metadata: nil, completion:
{ (metadata, error) in
if error != nil {
print(error!)
return
}
print(metadata!)
if let progileImageURL = metadata?.downloadURL()?.absoluteString {
let values = ["name": name, "email": email, "profileImageUrl": progileImageURL]
self.registerUserIntoDatabaseWithUID(uid: uid, values: values as [String : AnyObject])
}
})
}
}
}
func registerUserIntoDatabaseWithUID(uid: String, values: [String: AnyObject]) {
let ref = Database.database().reference()
let userRef = ref.child("users").child(uid)
userRef.updateChildValues(values, withCompletionBlock: { (err, ref) in
if err != nil {
print(err!)
return
}
print("Saved user successfully into Firebase db")
self.messagesController1?.checkIfUseLoggedin()
self.dismiss(animated: true, completion: nil)
})
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
var selectedImageFromPicker: UIImage?
if let editedImage = info["UIImagePickerControllerEditedImage"] as? UIImage {
selectedImageFromPicker = editedImage
print(editedImage)
}
else if let orignalImage = info["UIImagePickerControllerOriginalImage"] as? UIImage {
selectedImageFromPicker = orignalImage
print(orignalImage)
}
if let selectedImage = selectedImageFromPicker {
self.profileImageView.image = selectedImage
}
self.dismiss(animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
print("picker cancled")
self.dismiss(animated: true, completion: nil)
}
