The document provides an overview of the iPhone X and iOS 11, highlighting differences in screen size and layout recommendations for a full-screen experience. It discusses artwork specifications, safe areas for content placement, and features like Face ID for authentication and enhanced multitasking capabilities on iPad. Additionally, it details the use of Core ML for machine learning and ARKit for augmented reality applications.

5. Artwork Recommendations
• Apple recommends using:
• Resolution-independent PDFs for glyphs and flat, vector artwork
• Starting with Xcode 9 and iOS 11, appropriately sized PNGs
will be rendered at runtime
• High resolution PNGs with 2.0 and 3.0 scale factors for
rasterized images
• In practice, it may still be preferable to use PNGs if different images
are needed for different resolutions or if assets are to be shared
with Android apps

6. Layout:
Provide a full screen experience

7. Layout:
Inset essential content to prevent clipping

8. Layout:
Be mindful of the status bar height
With In-Call Status BarStandard

9. Layout:
Reconsider Hiding the Status Bar

10. Layout: Be mindful of aspect ratio differences
when reusing existing artwork

Make sure that important visual content is visible on
both device display sizes.

Make sure that important visual content is visible on
both device display sizes.

12. Layout:
Additional Considerations
The device has round
corners. Do not try to
hide or emphasize them.
The Home indicator should
neither be hidden nor
emphasized.
Avoid custom gestures at
the bottom of the screen
Avoid placing interactive
controls in the far corners
of the screen
Do not disable auto-hiding of
the Home screen indicator

13. Safe Area and Margins
• iOS 7 introduced the top and bottom layout guides to
assure content is never rendered underneath top and
bottom bars (status, navigation, tab, etc.)
• iOS 11 introduces the additional concept of Safe Areas
which further ensure that content is appropriately inset
both horizontally and vertically on the device
• The safe area prevents content from underlapping top
and bottom bars, sensor housing and other areas
obscured on the display

18. Color:
Use wide color to enhance the visual experience
iPhone 7, iPhone 8 and iPhone X all
support the P3 color space

19. Accurately reference authentication methods
iPhone X supports Face ID for authentication.
Don’t refer to Touch ID on iPhone X.

20. iOS 11

21. iPad:
Multitasking, Drag and Drop
• All new multitasking view
• Dock available from anywhere via swipe-up gesture
• Drag and Drop enables moving text, images and files
between apps
• Supports Multi-Touch to select multiple items, even
across apps
• Spring-loading lets you drag and drop items to an app by
hovering over the app’s icon in the Home screen or Dock

22. Core ML:
Machine Learning
• Provides an engine which can process a variety of machine
learning models in apps
• Operates on a model created and trained during
development
• Takes advantage of the CPU and GPU to provide high-
performance and efficient computing
• Support for computer vision and natural language processing
• Used across Apple’s product line, including Siri, Camera, and
QuickType

23. ARKit:
Augmented Reality
• Uses Visual Inertial Odometry (VIO) to combine camera sensor data and
CoreMotion data
• Apps can determine, with a high degree of accuracy, how the device is moving
within a room
• Scenes from the camera are analyzed to find horizontal planes, such as tables
and floors
• Objects can be tracked and placed within the scene
• Estimates the total amount of light in the room so the correct amount of light
may be applied to virtual objects
• The TrueDepth Camera on iPhone X allows for detecting the position, topology
and expression of a user’s face in real time
