If you just want to check if Stage Manager is enabled this code might help.
But, this process is not perfect.
can not switch on/off.
// AppDelegate version
var isStageManager: Bool {
guard UIDevice.current.userInterfaceIdiom == .pad,
let appDelegate = UIApplication.shared.delegate as? AppDelegate,
let screenHeight = appDelegate.window?.windowScene?.screen.bounds.height,
let windowHeight = appDelegate.window?.bounds.height else { return false }
return screenHeight > windowHeight
}
// SceneDelegate version
var isStageManager: Bool {
guard UIDevice.current.userInterfaceIdiom == .pad,
let sceneDelegate = UIApplication.shared.connectedScenes.first?.delegate as? SceneDelegate,
let screenHeight = sceneDelegate.window?.windowScene?.screen.bounds.height,
let windowHeight = sceneDelegate.window?.bounds.height else { return false }
return screenHeight > windowHeight
}
