An unchanged App which run fine in < iOS 15 versions crashes directly on startup in iOS 15.0.1.

Reason is unclear for me. Tried debugging in Xcode 13 - no hints at all. Has someone an idea?

Not sure you crashed in AppDelegate, that's only the point where debugger returns after crash.

Did you try a Clean Build Folder ?

You should show some code:

Complete code of SceneDelegate
Complete code of ContentView (the one called in SceneDelegate)
info.plist

That will help investigate the problem.

Yes, I tried everything. Cleaning build folder of course, several times. I appreciate your help - sorry for the delayed answer!!

SceneDelegate:

import UIKit

import SwiftUI



class SceneDelegate: UIResponder, UIWindowSceneDelegate {



    var window: UIWindow?





    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {

        // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.

        // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.

        // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).



        

        // Create the SwiftUI view that provides the window contents.

//        let contentView = ContentView() // übergebe Daten

        

        let contentView = ContentView().environmentObject(GlobalData())

        

        // Use a UIHostingController as window root view controller.

        if let windowScene = scene as? UIWindowScene {

            let window = UIWindow(windowScene: windowScene)

            window.rootViewController = UIHostingController(rootView: contentView)

            self.window = window

            window.makeKeyAndVisible()

        }

    }



    func sceneDidDisconnect(_ scene: UIScene) {

        // Called as the scene is being released by the system.

        // This occurs shortly after the scene enters the background, or when its session is discarded.

        // Release any resources associated with this scene that can be re-created the next time the scene connects.

        // The scene may re-connect later, as its session was not neccessarily discarded (see `application:didDiscardSceneSessions` instead).

    }



    func sceneDidBecomeActive(_ scene: UIScene) {

        // Called when the scene has moved from an inactive state to an active state.

        // Use this method to restart any tasks that were paused (or not yet started) when the scene was inactive.

    }



    func sceneWillResignActive(_ scene: UIScene) {

        // Called when the scene will move from an active state to an inactive state.

        // This may occur due to temporary interruptions (ex. an incoming phone call).

    }



    func sceneWillEnterForeground(_ scene: UIScene) {

        // Called as the scene transitions from the background to the foreground.

        // Use this method to undo the changes made on entering the background.

    }



    func sceneDidEnterBackground(_ scene: UIScene) {

        // Called as the scene transitions from the foreground to the background.

        // Use this method to save data, release shared resources, and store enough scene-specific state information

        // to restore the scene back to its current state.

        

        // Schedule die nächste Background-App-Aufruf

//        (UIApplication.shared.delegate as! AppDelegate).scheduleBackgroundFetch()

    }

Same issue happen with me. Adding Display name explicitly fixed the issue for me. Select Target -> General and check display name is explicitly added.

Hi manish_cs!

MANY, MANY, MANY THANKS!!!!!

That did it! No crash at startup anymore - I was going crazy about this.

What a simple solution - it would have never came to my mind.

Alignments are broken in SWIFTUI still - but now i can work on it.

Strange behaviour: what was left aligned is sometime now center...
