SwiftUI Firebase Phone Auth Change DisplayName - firebase

Question

The displayName in the user parameter of the addStateDidChangeListener function in the listener function inside the SessionStore Class returns nil. But I am changing the displayName with the createProfileChangeRequest function. I have one problem. When I change the DisplayName, when I log in with the phone number for the first time, the displayName returns empty. However, when I log in with the application closed in the background, the displayName is full. What is the reason of this ? Where am I doing wrong?
Model:
struct User {
var uid: String
var displayName: String?
var phoneNumber: String?
var isAdmin: Bool
}
Session Store:
class SessionStore : ObservableObject {
var didChange = PassthroughSubject<SessionStore, Never>()
var handle: AuthStateDidChangeListenerHandle?
#Published var user: User?
#Published var uid: String = ""
#Published var errorMessage: String = ""
#Published var showAlert: Bool = false
#Published var isOpenHomePage: Bool = false
#Published var code: String = ""
func listener() {
handle = Auth.auth().addStateDidChangeListener { (auth, user) in
if let user = user {
self.user = User(uid: user.uid, displayName: user.displayName, phoneNumber: user.phoneNumber ?? "", isAdmin: false)
} else {
self.user = nil
}
}
}
func verifyPhoneNumber(phoneNumber: String) {
PhoneAuthProvider.provider().verifyPhoneNumber("+90\(phoneNumber)", uiDelegate: nil) { ID, error in
if error != nil {
self.errorMessage = error?.localizedDescription ?? ""
self.showAlert = true
print("erroroo: \(self.errorMessage)")
return
}
self.uid = ID ?? ""
}
}
func credentialProviderPhoneNumber() {
let credential = PhoneAuthProvider.provider().credential(withVerificationID: uid, verificationCode: code)
Auth.auth().signIn(with: credential) { result, error in
if error != nil {
self.errorMessage = error?.localizedDescription ?? ""
print("error mesajı: \(self.errorMessage)")
return
}
self.isOpenHomePage = true
}
}
func signOut () {
do {
try Auth.auth().signOut()
self.user = nil
} catch {
}
}
func unbind () {
if let handle = handle {
Auth.auth().removeStateDidChangeListener(handle)
}
}
func createProfileChangeRequest() {
let changeRequest = Auth.auth().currentUser?.createProfileChangeRequest()
changeRequest?.displayName = "Test 123"
changeRequest?.commitChanges(completion: { error in
print("hata: \(error?.localizedDescription)")
})
}
}
