Debug iOS apps and profile performance using LLDB, the interactive Memory Graph Debugger, and Instruments. Use for crashes, retain-cycle inspection, hangs, build failures, and generic CPU, memory, energy, or network profiling. Use ios-memgraph-analysis for .memgraph capture, leaks CLI ownership paths, or persistent heap growth; use ios-ettrace-performance for ETTrace capture and JSON.

When to use

• LLDB debugging
• Memory Graph Debugger workflow
• Retain cycle inspection
• Hang diagnostics
• Build failure triage
• Instruments overview
• CPU profiling
• Memory profiling

When not to use

• .memgraph capture
• leaks CLI ownership paths
• persistent heap growth
• ETTrace capture
• ETTrace JSON
