Hi Peter, its me again. Im having a problem and didn't find an answer anywhere. First of all, I would like to apologize you
for posting this question here, but I didn't know where to post. After implementing some iOS 14 code, I updated my entire code to iOS 14 (before it was 13). But, with it came lot of error messages, with which I accidentally delete some stuff that stopped my code from updating when I changed it (it sucks that I didn't have any backup, and the ones I have appears to inherit the same errors). Then, I decided to create a new project, and add everything back again. However, the overall appearance of Xcode changed and I'm having problems in fixing them. The first one in related to the new @main struct (mine called MedicalApp). Before,in my code, the initial view was ContenView and it was exactly like this:
struct ContentView: View {
@EnvironmentObject var session: SessionStore
func getUser() {
session.listen()
}
var body: some View {
Group {
if (session.session != nil) {
HomeView()
}
else {
SigninOrSignUp()
}
}
.onAppear(perform: getUser)
}
}
Now, it appears that the main struct has changed to "projectName"App. Mine, is this one:
@main
struct MedicalApp: App{
@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
var body: some Scene{
WindowGroup{
ContentView()
}
}
}
With the same ContentView code as before.
These are my SessionStore, AppDelegate, SceneDelegate and SignInOrSignUpView that I copied exactly like the other code (you might have them from when I shared my code with you):
class SessionStore: ObservableObject{
var didChange = PassthroughSubject<SessionStore, Never>()
var session: User? {didSet {self.didChange.send(self)}}
@Published var handle: AuthStateDidChangeListenerHandle?
func listen() {
handle = Auth.auth().addStateDidChangeListener({ (auth, user) in
if let user = user {
self.session = User(uid: user.uid, email: user.email)
}
else {
self.session = nil
}
})
}
func signUp(email: String, password: String, handler: @escaping AuthDataResultCallback) {
Auth.auth().createUser(withEmail: email, password: password, completion: handler)
}
func sigIn(email: String, password: String, handler: @escaping AuthDataResultCallback){
Auth.auth().signIn(withEmail: email, password: password, completion: handler)
}
func signOut() {
do {
try Auth.auth().signOut()
self.session = nil
}
catch {
print("Erro ao sair")
}
}
func showError(_ message: String) {
}
func unbind() {
if let handle = handle{
Auth.auth().removeStateDidChangeListener(handle)
}
}
deinit {
unbind()
}
}
class AppDelegate: UIResponder, UIApplicationDelegate , GIDSignInDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
GIDSignIn.sharedInstance().clientID = FirebaseApp.app()?.options.clientID
GIDSignIn.sharedInstance().delegate = self
return true
}
func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any])
-> Bool {
return GIDSignIn.sharedInstance().handle(url)
}
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error?) {
// ...
if let error = error {
print(error.localizedDescription)
return
}
guard let authentication = user.authentication else { return }
let credential = GoogleAuthProvider.credential(withIDToken: authentication.idToken,
accessToken: authentication.accessToken)
Auth.auth().signIn(with: credential) { (res, err) in
if err != nil{
print((err?.localizedDescription)!)
return
}
print("usuário=" + (res?.user.email)!)
}
}
func sign(_ signIn: GIDSignIn!, didDisconnectWith user: GIDGoogleUser!, withError error: Error!) {
// Perform any operations when the user disconnects from app here.
// ...
}
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
}
}
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
let contentView = ContentView()
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: contentView.environmentObject(SessionStore()))
self.window = window
window.makeKeyAndVisible()
}
}
func sceneDidDisconnect(_ scene: UIScene) {
}
func sceneDidBecomeActive(_ scene: UIScene) {
}
func sceneWillResignActive(_ scene: UIScene) {
}
func sceneWillEnterForeground(_ scene: UIScene) {
}
func sceneDidEnterBackground(_ scene: UIScene) {
}
}
struct SigninOrSignUp: View {
var body: some View {
ZStack{
LinearGradient(gradient: .init(colors: [Color("Color"),Color("Color1"),Color("Color2")]), startPoint: .top
, endPoint: .bottom)
.edgesIgnoringSafeArea(.all)
if UIScreen.main.bounds.height > 800{
SignView()
}
else{
ScrollView(.vertical, showsIndicators: false) {
SignView()
}
}
}
}
}
*SignView is the main view for Signin and Signup
*Above AppDelegate, I had @UIApplicationMain. It had to be deleted because there was an error saying there were multiple main (possibly referring to @main in struct MedicalApp: App).
The building succeeds, but the screen starts all white and then turns to all black.
Questions:
Do I need to maintain "projectName"App? If I delete it, how to turn ContentView the main one (tried @main but didn't work because it needed a main static function)?
How to fix these problem? How to make them work again?
--> If you still have the code I shared with you it would be great if you shared it back with me, as I deleted the repo because it was public.
