Xcode 11•Swift 5.1

extension UIDevice {
    var iPhoneX: Bool { UIScreen.main.nativeBounds.height == 2436 }
    var iPhone: Bool { UIDevice.current.userInterfaceIdiom == .phone }
    var iPad: Bool { UIDevice().userInterfaceIdiom == .pad }
    enum ScreenType: String {
        case iPhones_4_4S = "iPhone 4 or iPhone 4S"
        case iPhones_5_5s_5c_SE = "iPhone 5, iPhone 5s, iPhone 5c or iPhone SE"
        case iPhones_6_6s_7_8 = "iPhone 6, iPhone 6S, iPhone 7 or iPhone 8"
