How to programmatically detect iPhone XS or iPhone X?

Question

One of my apps connects to a web app service that delivers device specific news to to the user. To adapt this to the latest iPhone versions I need to programmatically distinguish between the iPhone XS and iPhone X. How can this be done?

[[UIScreen mainScreen] bounds].size was always a good starting point to tell the different devices apart. However, iPhone XS and iPhone X have the same screen dimensions: 1125 x 2436. Thus using [[UIScreen mainScreen] bounds].size does not work in this case.

Is there any other method to detect the latest iPhone versions?

EDIT: This is NOT a duplicate of the question "How to detected iPhone X" since all answers/solutions discussed there use the screen dimensions to specify the device type. As described above iPhone X and iPhone XS have the exact same dimensions and thus the solutions cannot tell these two apart...

Solution 1

I use DeviceUtil to determine an iOS device's model.

According to this DeviceUtil GitHub post, the returned UIDevice hardwareString values are:

iPhone11,2 = iPhone XS
iPhone11,4 = iPhone XS Max
iPhone11,8 = iPhone XR

Curiously, the Xcode 10 GM Simulator's [UIScreen mainScreen].bounds.size returns 375 x 812 for iPhone X, XS, XS Max, and R devices. I had expected 414 x 896 for the XS Max and XR.

You can determine using UIScreen.main.nativeBounds.

 if UIDevice().userInterfaceIdiom == .phone {
        switch UIScreen.main.nativeBounds.height {
        case 1136:
            print("IPHONE 5,5S,5C")
        case 1334:
            print("IPHONE 6,7,8 IPHONE 6S,7S,8S ")
        case 1920, 2208:
            print("IPHONE 6PLUS, 6SPLUS, 7PLUS, 8PLUS")
        case 2436:
            print("IPHONE X, IPHONE XS, IPHONE 11 PRO")
        case 2688:
            print("IPHONE XS MAX, IPHONE 11 PRO MAX")
        case 1792:
            print("IPHONE XR, IPHONE 11")
        default:
            print("UNDETERMINED")
        }
    }

.nativeBounds won't change even if the orientation is changed. https://developer.apple.com/documentation/uikit/uiscreen/1617810-nativebounds

#import <sys/utsname.h> // import it in your header or implementation file.

+(NSString*)deviceName
{
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *machineName = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];


    NSDictionary *commonNamesDictionary =

    NSString *deviceName = commonNamesDictionary[machineName];

    if (deviceName == nil) {
        deviceName = machineName;
    }

    return deviceName;
}

It will return device model for you ,also included XS, XR, XS Max

    #define IS_IPHONE_6PLUS  (IS_IPHONE && [[UIScreen mainScreen] nativeScale] == 3.0f)
    #define IS_IPHONE_6_PLUS (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 736.0)
    #define IS_IPHONE_X      (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 812.0)
#define IS_IPHONE_X      (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 812.0)

    #define IS_IPHONE_XS      (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 812.0)
    #define IS_IPHONE_X_MAX      (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 896.0)
    #define IS_RETINA        ([[UIScreen mainScreen] scale] >= 2.0) // 3.0 for iPhone X, 2.0 for others

    #define IS_IPAD_DEVICE   [(NSString*)[UIDevice currentDevice].model hasPrefix:@"iPad"]

Note:- Be careful, it works fine only for portrait orientation

I found that the Simulator reported these sizes because my app targets iOS 10 or later. To enable full screen resolution, my app must target iOS 11 or later.

[cmii]

Your app must target iOS 10 or later AND, must use launch screen file instead launch image source.

[lifjoy]

You are correct about the launch image. But I think iOS 11 is also needed. On developer.apple.com/iphone, there's a paragraph that says "Your app will run in Full Screen Display Mode on iPhone X, iPhone XS, iPhone XS Max, and iPhone XR if your project’s base SDK is set to iOS 11 or later and you have a Launch Storyboard or iPhone X launch image". My app targets iOS 10 AND does have the proper XS Max launch image, but its still scaled on the XS Max.

[cmii]

I'm working with last Xcode, iOS 10 target, with full screen presentation ON, and [UIScreen mainScreen].bounds.size returns the correct size for all devices.

[lifjoy]

Thanks, @cmii. You are so right. Turns out that I botched the new UILaunchImages dictionary that I added to support {414, 896}, LaunchImage-iPhone6_5-Port. Simulator is now returning the expected screen sizes.

[Coder221]

XR is bigger than XS, are you sure that XR height ins 1792?

[Umair]

Yes you are right but this is the value that the nativeBounds method returns for XR.

[M Afham]

Is this works in landscape mode?

[Umair]

Yes it would work for landscape mode too.
