Current User not being set? - ios

Question

So I am having an issue with my code. My signup page grabs the user data. It gets the username, location, and profile pic. Everything works right it seems everything is being saved to firebase. However when the account is created and I go to the user profile everything seems to be nil.
This is my function that handles the sign up.
#objc func handleSignUp(){
// first we cant to take sure that all of the fields are filled
let bio: String = ""
var profilePic: String = ""
// will take the user selected image and load it to firebase
let imageName = NSUUID().uuidString
let storageRef = Storage.storage().reference().child("profile_images").child("\(imageName).PNG")
if let userImage = selectedImageFromPicker,let uploadData = UIImageJPEGRepresentation(userImage, 0.1){
storageRef.putData(uploadData, metadata: nil, completion: { (metadata, error) in
if error != nil{
print(error ?? "")
return
}
profilePic = (metadata?.downloadURL()!.absoluteString)!
guard let username = self.nameTextField.text,
let confirmPassword = self.confirmPasswordTextField.text,
let email = self.emailTextField.text,
let password = self.passwordTextField.text,
!username.isEmpty,
!email.isEmpty,
!password.isEmpty,
!confirmPassword.isEmpty
else {
print("Required fields are not all filled!")
return
}
if self.validateEmail(enteredEmail:email) != true{
let alertController = UIAlertController(title: "Error", message: "Please Enter A Valid Email", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "Ok", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
// will make sure user is validated before it even tries to create user
// will make sure the password and confirm password textfields have the same value if so it will print an error
if self.passwordTextField.text != self.confirmPasswordTextField.text {
let alertController = UIAlertController(title: "Error", message: "Passwords Don't Match", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "Ok", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
// will authenticate a user into the authentication services with an email and passowrd
AuthService.createUser(controller: self, email: email, password: password) { (authUser) in
guard let firUser = authUser else {
return
}
//will add user to the database
print(profilePic)
print(username)
UserService.create(firUser, username: username , profilePic: profilePic , bio: bio, location: self.userLocation!) { (user) in
guard let user = user else {
print("User successfully loaded into firebase db")
return
}
// will set the current user for userdefaults to work
print(user.profilePic)
print(user.username)
User.setCurrent(user, writeToUserDefaults: true)
// self.delegate?.finishSigningUp()
self.finishSigningUp()
}
}
})
}
}
This is my viewdidload for the profile controller. When I print out the user here everything is nil.
override func viewDidLoad() {
super.viewDidLoad()
collectionView?.backgroundColor = UIColor.white
let user = self.user ?? User.current
profileHandle = UserService.observeProfile(for: user) { [unowned self](ref, user, events) in
self.profileRef = ref
self.user = user
self.userEvents = events
// self.jobs = allJobs
// self.reciepts = allReciepts
// print(self.userEvents)
// print(self.reciepts)
DispatchQueue.main.async {
self.collectionView?.reloadData()
}
}
This handles the transition to the homepage.
func finishSigningUp() {
print("Finish signing up from signup view controller")
print("Attempting to return to root view controller")
let homeController = HomeViewController()
//should change the root view controller to the homecontroller when done signing up
self.view.window?.rootViewController = homeController
self.view.window?.makeKeyAndVisible()
}
My home view controller controls the navigation of these throguh a snapcaht style swiping which is controlled using an array of view controllers. Like so
lazy var viewControllerList: [UIViewController] = {
let homeFeedController = HomeFeedController()
let navController = UINavigationController(rootViewController: homeFeedController)
// let navController = ScrollingNavigationController(rootViewController: homeFeedController)
let profileView = ProfileeViewController(collectionViewLayout: UICollectionViewFlowLayout())
let profileViewNavController = UINavigationController(rootViewController: profileView)
let searchController = EventSearchController(collectionViewLayout: UICollectionViewFlowLayout())
let searchNavController = UINavigationController(rootViewController: searchController)
return [searchNavController,navController,profileViewNavController]
}()
Obseverprofile function
// will observe the user object in the database for any changes and make sure that they are updated
static func observeProfile(for user: User, completion: #escaping (DatabaseReference, User?, [Event]) -> Void) -> DatabaseHandle {
// 1
let userRef = Database.database().reference().child("users").child(user.uid)
// 2
return userRef.observe(.value, with: { snapshot in
// 3
guard let user = User(snapshot: snapshot) else {
return completion(userRef, nil, [])
}
// print(user)
// 4
Events(for: user, completion: { events in
// 5
completion(userRef, user, events)
})
})
}
