# iOS Button Guidelines
Buttons are essential interactive elements in iOS apps that allow users to trigger actions.
## Design Principles
- Follow Apple's design guidelines
- Ensure accessibility compliance
- Use appropriate sizing for touch targets
## Implementation
Use UIButton class for standard button implementations.

# iOS Interface Guidelines
Apple's iOS provides comprehensive design guidelines for creating
intuitive and accessible user interfaces. These guidelines ensure
consistency across all iOS applications.
## Key Principles
- Clarity: Text is legible at every size
- Deference: Fluid motion and crisp, beautiful interface
- Depth: Visual layers and realistic motion
