iPhone X is already here redesigning the way the content is displayed and creating a brand-new experience. It has an edge to edge Super Retina Display with a resolution of 1125×2436 px. iPhone X features a special cut-out at the top of the screen. Thus designing apps for this futuristic machine brings new challenges as well as opportunities. Let’s learn how to design an app or game to feel and look great on iPhone X.
Screen Sizes

The good news is if you have a native app for iOS, you don’t have to make any changes - the app will be automatically adopted for the new iPhone X. All navigation bars, collection views, tables, and tab bars will be automatically positioned. When designing, you must ensure that the layouts fit the screen perfectly. If your app has a custom layout, you may need to update it for the new iPhone X. With the Auto Layout, everything will be easy.

Center your content
The device features new sensors and particular screen corners so make sure that your UI won’t get clipped. Speaking about the content, it’s preferable to place it in the center with symmetrical insets. Again with the Auto Layout, your content will be automatically adapted to the safe area of iPhone X. Nothing will be hidden behind round corners, home indicator or sensors.

Note, Apple highly recommend not to hide the cut-out and curved edges. So forget about placing black bars.
Brand-new status bar

Due to the sensors, the new bar has got 2 parts. It has become nearly 2x taller than on iPhone 6,7, and 8 (previously it was 20 pt, and now it’s 44 pt). So if your app features a fixed status bar and content just below it, consider updating the app in order not lose anything. Again, don’t forget about the safe area while designing a new app or iOS.
Moreover, the status bar should be visible all time. Since the screen is bigger and taller, it would be a good idea to unhide the bar. It is essential to point, that the new status bar doesn’t change its height when the device records voice or tacks the location.
Where to place interactive controls?
Since the physical home button was replaced by the home indicator, the place of interactive controls should be changed. There should be more space for gestures and swiping up around the home indicator. And if there are interactive controls, how will the user go back to the home screen? The users may accidentally use swiping up, and the UI of an app will be difficult to reach since every time they swipe, they will go back to the home screen.
However, you should and have to use the function bars and tab bars but try not to interfere with the home indicator.

Smart home indicator
iPhone X features a redesigned home indicator. Apple decided to opt out of a physical home button. It’s a small white line on the bottom of the screen. To get back to the homescreen, you can swipe up from any app.
With the new iOS, the users get an adoptive home indicator which hides automatically when the screen is inactive and appears when you relaunch the app. This function comes in handy when listing photos or watching videos. Besides the auto-hide, the home indicator adapts to the color of your app’s background and changes it automatically.
With the new smart home indicator, there is no place for button pressing, everything is controlled by gestures. Moreover, you can use custom gestures in games as well as set own gestures to control the device.
More colors than ever before
iPhone X features the new Super Retina Display with the support of P3 colors. And it means that the colors are richer and more saturated when compared to the older devices.
Improved security with Face ID
Previously, iPhones were fitted with Touch ID. And iPhone X features Face ID for authentication to keep your data secure. Face ID features state-of-the-art algorithms to scan your face and unlock iPhone X. In case your app needs Apple Pay or other identifications, don’t integrate Touch ID for that, take advantage of the new technology brought up by Apple.
Video
The new screen of iPhone X changes the way video is played on the device. The system video player has two viewing modes - full-screen and fit-to-screen. Make sure that all custom video players behave as expected. The video should fill the display when played. If it fails, it may result in too much cropping. Moreover, it would be great if the users will be able to switch between two viewing modes.
Apple advises keeping the original aspect ratio since the iOS won’t be able to scale the video based on the viewing mode correctly.

Where can I preview my app UI for iPhone X?
The good news is you can use Xcode 9 stimulator to preview your app. And check if something needs to be updated for iPhone X.
In a nutshell
Though the new iPhone X stands out from the crowd providing absolutely new user experience, designing apps for iPhone X is still a smooth sail. Take care of the new display capabilities and its dimensions and make most of them.
