I'm using **Libgdx**, input events don't work when using **Multi-OS Engine** - ios

Question

It works fine in Android and Desktop. But when running on iOS, it doesn't respond any input event.
I'm using gdxVersion 1.9.5, multi-os engine 1.2.3
I wrote a test class extends input adapter and override touchDown and touchUp method. But it doesn't respond any of the input events which work fine in Android.
public class TestScreen extends ScreenAdapter implements InputProcessor {
private CardGame game;
private OrthographicCamera guiCam;
public TestScreen(CardGame game){
this.game = game;
guiCam = new OrthographicCamera(Consts.WORLD_WIDTH, Consts.WORLD_HEIGHT);
Gdx.input.setInputProcessor(this);
}
public void draw () {
GL20 gl = Gdx.gl;
gl.glClearColor(1, 0, 0, 1);
gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
guiCam.update();
}
public void render (float delta) {
draw();
}
#Override
public boolean keyDown(int keycode) {
System.out.println("key down");
return true;
}
#Override
public boolean keyUp(int keycode) {
System.out.println("key up");
return true;
}
#Override
public boolean keyTyped(char character) {
System.out.println("key typed");
return true;
}
#Override
public boolean touchDown(int screenX, int screenY, int pointer, int button) {
System.out.println("touch down");
return true;
}
#Override
public boolean touchUp(int screenX, int screenY, int pointer, int button) {
System.out.println("touch up");
return true;
}
#Override
public boolean touchDragged(int screenX, int screenY, int pointer) {
System.out.println("touch dragged");
return true;
}
#Override
public boolean mouseMoved(int screenX, int screenY) {
System.out.println("mouse moved");
return true;
}
#Override
public boolean scrolled(int amount) {
System.out.println("scrolled");
return true;
}
}
