iOS: Detect if the device is iPhone X family (frameless)

Question

In my app there is some logic for frameless devices (iPhoneX, Xs Xs max, Xr). Currently it works base on the model of the devices, so, I detect the model by DeviceKit framework.

Answer 1

This is valid for any orientation. No need to worry about iOS version before 11.0 since iPhone X minimum version is 11.0. Source

extension UIDevice {

    var hasNotch: Bool {
        if #available(iOS 11.0, *) {
           return UIApplication.shared.keyWindow?.safeAreaInsets.bottom ?? 0 > 0
        }
        return false
   }
}
