Mobile App Debugging

This handles the annoying platform-specific bugs that only show up on actual devices. You get debugging workflows for both iOS (Xcode memory graphs, device logs, SIGABRT crashes) and Android (logcat, ADB commands, ANR handling), plus guidance on cross-platform issues like network conditions and device constraints. The reference guides break down concrete scenarios like memory leaks, background task failures, and permission problems. Honestly most useful when you're past the "works on simulator" stage and dealing with real device weirdness. The checklist format makes it easy to systematically work through mobile-specific problems instead of randomly trying fixes.

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
