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

extension UIDevice {
    var hasNotch: Bool
    {
        if #available(iOS 11.0, *)
        {
            let bottom = UIApplication.shared.keyWindow?.safeAreaInsets.bottom ?? 0
            return bottom > 0
        } else
        {
            // Fallback on earlier versions
            return false
        }
    }
}

Using by

if UIDevice.current.hasNotch 
{
    //... consider notch
} 
else 
{
   //... don't have to consider notch
}
