How to detect an Iphone X programmatically?

Swift and Objective-C developer tutorial on how to detect if an app is running on iPhone X
12 October 2017   3576

If you have an iOS app, now, with release of iPhone X you can face some new issues. In this tutorial, we will show you how to programmatically detect if an application is running on iPhone X.

Unfortunatelly, there is no direct methods on how to solve this issue. But let's use backdoor. Iphone X screen is 1125px X 2436px. So, we can use this information to solve this task.

Swift 3 and upper

if UIDevice().userInterfaceIdiom == .phone {
        switch UIScreen.main.nativeBounds.height {
        case 1136:
            print("iPhone 5 or 5S or 5C")
        case 1334:
            print("iPhone 6/6S/7/8")
        case 2208:
            print("iPhone 6+/6S+/7+/8+")
        case 2436:
            print("iPhone X")

Objective C

    if([[UIDevice currentDevice]userInterfaceIdiom]==UIUserInterfaceIdiomPhone) {

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

            case 1136:
                printf("iPhone 5 or 5S or 5C");
            case 1334:
                printf("iPhone 6/6S/7/8");
            case 2208:
                printf("iPhone 6+/6S+/7+/8+");
            case 2436:
                printf("iPhone X");

or use screenSize.height as float 812.0f not int 812   

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
    CGSize screenSize = [[UIScreen mainScreen] bounds].size;
    if (screenSize.height == 812.0f)
        NSLog(@"iPhone X");


DO NOT use the userInterfaceIdiom property to identify the device type, as the apple documentation explains,

For universal applications, you can use this property to tailor the behavior of your application for a specific type of device. For example, iPhone and iPad devices have different screen sizes, so you might want to create different views and controls based on the type of the current device.

Apple documentation

This property is just used to identify the running app's view style. However, the iPhone app (not the universal) could be installed in iPad device via App store, in that case, the userInterfaceIdiom will return the UIUserInterfaceIdiomPhone, too.

The right way is to get the machine name via uname.
