Hey y'all.
I have an error that is popping up when I go run the app. The error states:
Thread 1: Fatal error: No ObservableObject of type AccountCreationViewModel found. A View.environmentObject(_:) for AccountCreationViewModel may be missing as an ancestor of this view.
This is the file that the error come in:
import SwiftUI
struct RegisterView: View {
@EnvironmentObject var accountCreation: AccountCreationViewModel
init() {
UITextView.appearance().backgroundColor = .clear
}
var body: some View {
VStack {
Image("SMK")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(height: UIScreen.main.bounds.height / 3.5)
.cornerRadius(100)
.padding(.top, 50)
ZStack{
if accountCreation.pageNumber == 0{
SignView()
.environmentObject(AccountCreationViewModel())
}
else if accountCreation.pageNumber == 1{
Register()
.transition(.move(edge: .trailing))
}
else {
ImageRegister()
}
}
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(Color.white).ignoresSafeArea(.all, edges: .bottom)
.clipShape(CustomCorners(corners: [.topLeft, .topRight]))
}
.background(Color(red: 22/255, green: 22/255, blue: 24/255))
.ignoresSafeArea(.all, edges: .all)
.alert(isPresented: $accountCreation.alert, content: {
Alert(title: Text("Error"), message: Text(accountCreation.alertMsg), dismissButton: .default(Text("Ok")))
})
}
}
struct RegisterView_Previews: PreviewProvider {
static var previews: some View {
RegisterView()
.environmentObject(AccountCreationViewModel())
}
}
This is the data model:
import SwiftUI
import Firebase
import CoreLocation
class AccountCreationViewModel: NSObject,ObservableObject, CLLocationManagerDelegate {
@Published var name = ""
@Published var location = ""
@Published var age = ""
@Published var phNumber = ""
@Published var code = ""
@Published var pageNumber = 0
@Published var images = Array(repeating: Data(count: 0), count: 4)
@Published var picker = false
@Published var alert = false
@Published var alertMsg = ""
@Published var isLoading = false
@Published var CODE = ""
@AppStorage ("log_Status") var status = false
func login(){
Auth.auth().settings?.isAppVerificationDisabledForTesting = true
isLoading.toggle()
PhoneAuthProvider.provider().verifyPhoneNumber("+" + code + phNumber, uiDelegate: nil) { (CODE,err) in
if err != nil {
self.alertMsg = err!.localizedDescription
self.alert.toggle()
return
}
self.CODE = CODE!
let alertView = UIAlertController(title: "Verification", message: "Please enter your OTP", preferredStyle: .alert)
let cancel = UIAlertAction(title: "Cancel", style: .destructive, handler: nil)

self.isLoading.toggle()
Auth.auth().signIn(with: credentials) { (res, err) in
self.isLoading.toggle()
if err != nil {
self.alertMsg = err!.localizedDescription
self.alert.toggle()
return
}
withAnimation(){
self.pageNumber = 1
}
}
}
}
alertView.addTextField() { (txt) in
txt.placeholder = "4860"
}
alertView.addAction(cancel)
alertView.addAction(ok)
UIApplication.shared.windows.first?.rootViewController?.present(alertView, animated: true, completion: nil)
}
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let last = locations.last!
CLGeocoder().reverseGeocodeLocation(last) { (places, _)
in guard let placeMarks = places else{return}
self.location = (placeMarks.first?.name ?? "") + ", " + (placeMarks.first?.locality ?? "")
}
}
func signUp(){
let storage = Storage.storage().reference()
let ref = storage.child("profile_Pics").child(Auth.auth().currentUser!.uid)
var urls : [String] = []
isLoading.toggle()
for index in images.indices{
ref.child("img\(index)").putData(images[index], metadata: nil) {
(_, err) in if err != nil{
self.alertMsg = err!.localizedDescription
self.alert.toggle()
self.isLoading.toggle()
return
}
ref.child("img\(index)").downloadURL {(url, _) in
guard let imageUrl = url else{return}
urls.append("\(imageUrl)")
if urls.count ==
self.images.count{
self.RegisterUser(urls: urls)
}
}
}
}
}
func RegisterUser(urls: [String]){
let db = Firestore.firestore()
db.collection("Users").document(Auth.auth().currentUser!.uid).setData([
"userName": self.name,
"location": self.location,
"age": self.age,
"imageUrls": urls
]) { (err) in
self.isLoading.toggle()
if err != nil{
self.alertMsg = err!.localizedDescription
self.alert.toggle()
return
}
self.status = true
}
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
}
func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) { if manager.authorizationStatus == .authorizedWhenInUse{ manager.requestLocation()
}
}
}
Since this is my first time using Firebase, it is hard for me to debug it. Can you please help me?
