I have recently bridged one of my apps to Mac via Catalyst. However, we noticed something strange: on Mac, formSheet modal presentation's animation is gone. When I call present, the animated parameter is true, and the transition style is the default, but there is no animation in Mac when presenting in; it just jumps right into view. When dismissing, though, it has a fade transition, although on iOS everything is perfectly fine and the transition is the default -- enter and exit from bottom of screen.

Here is a sample code: 

let controller = UIStoryboard(name: "Main", bundle: .main).instantiateViewController(withIdentifier: "MyViewController") as? MyViewController else { return }
let navigationController = UINavigationController(rootViewController: controller)
navigationController.modalPresentationStyle = .formSheet
present(navigationController, animated: true, completion: nil)

  • This seems to be default behaviour on macCatalyst builds... but hopefully they'll improve all these little differences with future updates. – Paul Martin May 06 '20 at 07:46
