Controlador de vista descarte muy rápido después de guardar en Firebase

Question

cada vez que trato de guardar algo en la base de firebase, mi controlador falla, la aplicación no falla y la información se guarda, pero el controlador de vista se descarta muy rápido cuando intento guardarlo incluso si no descarto la vc. ¡Gracias por tu ayuda!

Aquí está mi viewController:

Ejemplo 1:

import UIKit
import FirebaseAuth
import FirebaseDatabase
import FirebaseStorage
class EditAccountVC: UITableViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UITextFieldDelegate {
@IBOutlet var profileImage: UIImageView!
@IBOutlet var nameField: UITextField!
@IBOutlet var emailField: UITextField!
@IBOutlet var websiteField: UITextField!
var user: Users!
var imageChanged: Bool = false
override func viewDidLoad() {
super.viewDidLoad()
DataService.ds.REF_USERS.child((FIRAuth.auth()?.currentUser?.uid)!).observe(.value) { (snapshot: FIRDataSnapshot) in
if let postDict = snapshot.value as? Dictionary<String, AnyObject> {
let key = snapshot.key
self.user = Users(key: key, artistData: postDict)
}
if let user = self.user {
self.nameField.text = user.name
self.emailField.text = FIRAuth.auth()?.currentUser?.email
self.websiteField.text = user.website
self.profileImage.sd_setImage(with: URL(string: "/(self.user.profilePicUrl)") , placeholderImage: UIImage(named:"User-70") , options: .continueInBackground)
}
}
//profileImage.addObserver(self, forKeyPath: "image", options: .new, context: nil)
}
// override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
// print("IMAGE CHANGES")
// }
@IBAction func doneBtnTapped(_ sender: Any) {
let activityIndicator = UIActivityIndicatorView()
activityIndicator.hidesWhenStopped = true
activityIndicator.activityIndicatorViewStyle = .gray
let spinner: UIBarButtonItem = UIBarButtonItem(customView: activityIndicator)
self.navigationItem.rightBarButtonItem = spinner
activityIndicator.startAnimating()
let name = self.nameField.text!
let email = self.emailField.text!
let website = self.websiteField.text!
FIRAuth.auth()?.currentUser?.updateEmail(email, completion: { (error) in
if error != nil {
print(error!.localizedDescription)
}
})
let imageData = UIImageJPEGRepresentation(profileImage.image!, 1)
let imagePath = "profileImage/(user.userId)userPic.jpeg"
let imageRef = STORAGE.child(imagePath)
let metaData = FIRStorageMetadata()
metaData.contentType = "image/jpeg"
imageRef.put(imageData!, metadata: metaData) { (metaData, error) in
let changeRequest = FIRAuth.auth()?.currentUser?.profileChangeRequest()
changeRequest?.displayName = name
if let photoUrl = metaData!.downloadURL() {
changeRequest?.photoURL = photoUrl
}
changeRequest?.commitChanges(completion: { (error) in
if error == nil {
let user = FIRAuth.auth()!.currentUser!
let userInfo = ["email": email, "name": name, "website": website, "uid": user.uid, "profileImg": String(describing: user.photoURL!)] as [String : Any]
let userRef = DataService.ds.REF_USERS.child(user.uid)
userRef.updateChildValues(userInfo, withCompletionBlock: { (error, reference) in
})
}
})
}
}
@IBAction func editImageBtnTapped(_ sender: Any) {
let alert = Alerts()
alert.changeProfilePicture(self)
}
@IBAction func cancelBtnTapped(_ sender: Any) {
_ = navigationController?.popViewController(animated: true)
}
override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 1.0
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let image = info[UIImagePickerControllerEditedImage] as! UIImage
profileImage.image = image
self.imageChanged = true
picker.dismiss(animated: true, completion: nil)
}
}
