Can not launch ipad-iphone simulator in libgdx project - libgdx

Question

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.
Libgdx IOS main class is as follows:
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();
}
}
Error is as follows:
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.robovm.rt.VM.getStackClasses(II)[Ljava/lang/Class;

In fact, I prefer to run gradle.
But it throws error is as follows:
Executing external task 'launchIPhoneSimulator'...
