how do I set the size of a multi-platform app in xcode (spritekit) ? I know that you can't change the window size on iphone but this app is multi-platform and can also run on macos. So how do I set the window size and make it unable to be stretched but able to full-screen? (on macos) and I was also wandering is there was a way to select the window's starting position. Thanks! P.S. sorry for asking this stupid question just I'm a beginner so I don't know. I had tried searching for an answer but I did not find one.
