Forums > SwiftUI

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)

            let ok = UIAlertAction(title: "OK", style: .default) { (_) in

                if let otp = alertView.textFields![0].text{
                    let credentials = PhoneAuthProvider.provider().credential(withVerificationID: self.CODE, verificationCode: otp)

                    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?
