switch ((int)[[UIScreen mainScreen] nativeBounds].size.height) {

Based on your question as follow:
Or use screenSize.height as float 812.0f not int 812.
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
CGSize screenSize = [[UIScreen mainScreen] bounds].size;
// 812.0 on iPhone X, XS
// 896.0 on iPhone XS Max, XR.
if (screenSize.height >= 812.0f)
NSLog(@"iPhone X");
}

Swift:
Detect with topNotch:
If anyone considering using notch to detect iPhoneX, mind that on "landscape" its same for all iPhones.
var hasTopNotch: Bool {
if #available(iOS 13.0, *) {
return UIApplication.shared.windows.filter {$0.isKeyWindow}.first?.safeAreaInsets.top ?? 0 > 20
}else{
return UIApplication.shared.delegate?.window??.safeAreaInsets.top ?? 0 > 20
}
return false
}
Objective-C:
- (BOOL)hasTopNotch {
if (@available(iOS 13.0, *)) {
return [self keyWindow].safeAreaInsets.top > 20.0;
}else{
return [[[UIApplication sharedApplication] delegate] window].safeAreaInsets.top > 20.0;
}
return NO;
}
- (UIWindow*)keyWindow {
UIWindow *foundWindow = nil;
NSArray *windows = [[UIApplication sharedApplication]windows];
for (UIWindow *window in windows) {
if (window.isKeyWindow) {
foundWindow = window;
break;
}
}
return foundWindow;
