Launching Libgdx project to IPhonesimulator

Question

Im trying to make sure my app works on IOS. And doing so by trying to launch it to a IPhonesimulator on my mac.

doing:

./gradlew ios:launchIPhoneSimulator

Makes my app start on the simulator, the standard splashscreen by libgdx appears and then it shuts down and nothing more happends.

But when I build it ./gradlew ios:build ios:launchIPhoneSimulator I get these errors:

And here´s my IOSLauncher if its to any help..

public class IOSLauncher extends IOSApplication.Delegate {

@Override
protected IOSApplication createApplication() {
    IOSApplicationConfiguration config = new IOSApplicationConfiguration();
    return new IOSApplication(new MainClass(null,null), config);
}

public static void main(String[] argv) {
    NSAutoreleasePool pool = new NSAutoreleasePool();
    UIApplication.main(argv, null, IOSLauncher.class);
    pool.close();

}

}

Have you tried to launch through the IDE instead? You can get better logging that way, especially if you can click the project and Run As -> iOS Simulator App. Also you should not need the `ios:build` command. Finally, does the program work for the other platforms? — bazola, Jun 12 '15 at 18:39
Make sure you create a blank Xcode project and run it on a device or simulator first. — Tenfour04, Jun 13 '15 at 13:26

You simulator's audio output is borked. The openal audio toolkit is failing init which is causing everything to crash.

OK, but why does it happen and what should I do about it? Is this in no way caused by my code? – JohnyTex Oct 12 '15 at 18:10

When I had this happen to me, it was caused by my OSX host losing audio output after an update. I got my OSX host working with audio again and the issue with no audio in the simulator was resolved. Is your OSX host doing audio fine? – Michael Joyner Oct 12 '15 at 23:29
Actually no, it isn't, but it is strange that I only get the error intermittently(?) – JohnyTex Oct 13 '15 at 07:50

Yes, it does seem strange if it is intermittent, one would think it would be consistent, but I was using Mavericks at the time. My only suggestion is to get the audio on the OS-X host working and see if that helps. – Michael Joyner Oct 14 '15 at 12:16
