title: Can not launch ipad-iphone simulator in libgdx project
body: <p>I am developing a libgdx project. I want to deploy the project to android and ios. The project is working on desktop(MacOS) ,android simulator and android device. However, when I try to launch IOS simulators with gradle or main class, errors are throwed. Also I downloaded some another robovm example. These projects can launch simulators with similar code. </p>
  
  <p>Libgdx IOS main class is as follows:</p>
  
  <pre><code>public class IOSLauncher extends IOSApplication.Delegate {
  @Override
  protected IOSApplication createApplication() {
      IOSApplicationConfiguration config = new IOSApplicationConfiguration();
      return new IOSApplication(new DemoProject(), config);
  }
  
  public static void main(String[] argv) {
      NSAutoreleasePool pool = new NSAutoreleasePool();
      UIApplication.main(argv, null, IOSLauncher.class);
      pool.close();
  }
  }
  </code></pre>
  
  <p>Error is as follows:</p>
  
  <pre><code>Exception in thread "main" java.lang.UnsatisfiedLinkError: org.robovm.rt.VM.getStackClasses(II)[Ljava/lang/Class;

  <p>In fact, I prefer to run gradle.</p>
