A minimal iOS 13 app that is set up in Objective-C rather than using a storyboard and UIApplicationSceneManifest

main.m

@import UIKit;

@interface SceneDelegate : UIResponder <UIWindowSceneDelegate>
@end

@implementation SceneDelegate

@synthesize window = _window;

- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions {
    self.window = [[UIWindow alloc] initWithWindowScene:(UIWindowScene *)scene];
    self.window.rootViewController = [[UIViewController alloc] init];
    [self.window makeKeyAndVisible];
}

@end

@interface AppDelegate: UIResponder <UIApplicationDelegate>
@end

@implementation AppDelegate

- (UISceneConfiguration *)application:(UIApplication *)application configurationForConnectingSceneSession:(UISceneSession *)connectingSceneSession options:(UISceneConnectionOptions *)options {
    UISceneConfiguration *configuration = [[UISceneConfiguration alloc] init];
    configuration.delegateClass = SceneDelegate.class;
    return configuration;
}

@end

int main(int argc, char * argv[]) {
    return UIApplicationMain(argc, argv, nil, NSStringFromClass(AppDelegate.class));
}

Hey @douglashill 👋
Thanks for this code sample.
Do you know if it's possible to add more that one UIWindow to a scene at this point, so that you'd have two UIWindow objects in the view hierarchy?
I've been trying to get this working but to no avail.
Thanks!

I haven’t tried this.

👋 Got it working. It seems you need to assign any window reference to its own property for it to show up in the view hierarchy.

Thanks

works for me. except view controller views are all disabled. this problem ONLY occurs on iOS 13.

how were you able to enable the view control views ? , I am new to IOS development and i have been struggling to get the view controller views enabled :(

Good sample I would just change:

    self.window.rootViewController = [[UIViewController alloc] init];

to:

    self.window.rootViewController = [[NameOfYourViewController alloc]init];

Also don't forget to import #import "NameOfYourViewController.h"
