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 {
        let bottom = UIApplication.shared.keyWindow?.safeAreaInsets.bottom ?? 0
        return bottom > 0
    }
}

use 'UIDevice.current.hasNotch' will return true or false

Swift 5

var hasNotch: Bool {
    let bottom = UIApplication.shared.delegate?.window??.safeAreaInsets.bottom ?? 0
    return bottom > 0
}
