SOLVED: UITraitCollection: How to detect device orientation (Especially iPad)

Forums > iOS
@Gakkienl  HWS+

iPad has .regularWidth and .regularHeight for both landscape and portrait orientations. How can I determine the iPad being in landscape or portrait ?

Should have searched HWS first, think I must get somewhere with: https://www.hackingwithswift.com/example-code/uikit/how-to-read-the-interface-orientation-portrait-or-landscape

Still a question: traitCollection is available on a viewController, but I want to use it more generic and reusable in more place, so I thought about something like

///Helper to determine device type and orientation
enum DeviceType {
    private var traitCollection: UITraitCollection {
        return UITraitCollection()
    }
    static var isIpadLandscape: Bool {
        return (traitCollection.horizontalSizeClass == .regularWidth && traitCollection.verticalSizeClass == .regularHeight) &&
                UIApplication.shared.statusBarOrientation.isLandscape
    }
}

This doesn't work , any hints to push me in the right direction ?

This works:


///Helper to determine device type and orientation
enum DeviceTypeAndOrientation {
    static var isIpad: Bool {
        return UIView().traitCollection.horizontalSizeClass == .regular && UIView().traitCollection.verticalSizeClass == .regular
    }

    static var isLandscape: Bool {
        return UIApplication.shared.windows.first?.windowScene?.interfaceOrientation.isLandscape ?? false
    }
}

This works for me for now, but ... ... is this a neat way of doing things, or is it not done? Also I've read on several sites that using screen orientation is not done anymore on iOS devices, especially on iPads, in regards to multitasking/window, etc. Could someone point me in a direction of a better way to do this ?
