Just like in iOS. Use windowScene(_:didUpdate:interfaceOrientation:traitCollection:) in your window scene delegate, or implement viewWillTransition(to:with:) in your view controllers.

3And if it doesn't always seem to be resizing, especially when trying fullscreen, wrap whatever you are updating in `DispatchQueue.main.async { ... }`. – George May 08 '20 at 20:54

What if you're not using scenes in your app? – Oscar Jan 15 '21 at 03:33

I implemented my scaling calculations in viewWillTransitionTo and it works fine. – Oscar Jan 30 '21 at 19:22
