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

Since keyWindow was deprecated in iOS 13, based on the solution to find keyWindow from here, this one works for me

extension UIDevice {
    var hasNotch: Bool {
        if #available(iOS 11.0, *) {
            let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
            return keyWindow?.safeAreaInsets.bottom ?? 0 > 0
        }
        return false
    }

}
