Overview

Mobile app debugging addresses platform-specific issues, device hardware limitations, and mobile-specific network conditions.

When to Use

• App crashes on mobile
• Performance issues on device
• Platform-specific bugs
• Network connectivity issues
• Device-specific problems

Quick Start

Minimal working example:

Xcode Debugging:

Attach Debugger:
  - Xcode → Run on device
  - Set breakpoints in code
  - Step through execution
  - View variables
  - Console logs

View Logs:
  - Xcode → Window → Devices & Simulators
  - Select device → View Device Logs
  - Filter by app name
  - Check system logs for crashes

Inspect Memory:
  - Xcode → Debug → View Memory Graph
  - Identify retain cycles
  - Check object count
  - Monitor allocation growth
