With the iPhone X launch, the developer community faced some UI/UX challenges:
- The notch meant rethinking layouts and safe areas
- Face ID required API changes
- Aspect ratio changes broke some fixed UI designs
Apple’s Human Interface Guidelines became even more critical. One of the trickiest parts? Supporting edge-to-edge in landscape mode without layout bugs.
Xcode’s new simulators helped, but real-device testing was still essential. A reminder: hardware innovation often forces software evolution.
