I also encountered this issue. Noticed it was when displaying a map within a .pagesheet modal presentation. let vc = MapVC() vc.modalPresentationStyle = .pageSheet self.present(vc, animated: true) If I change modal presentation to .fullscreen, the warning disappear. let vc = MapVC() vc.modalPresentationStyle = .fullScreen self.present(vc, animated: true) With .pagesheet mode, the UIViewController is presented smaller than the full screen size. So I guess this warning is a bug in the mapkit library caused by this type of modal presentation style...

Dear, Did you found any solution to this issue ? Pierre
