Instruments Profiling
Performance profiling and stack analysis tool for native macOS and iOS applications using Instruments and xctrace CLI. Enables Time Profiler recording, process attachment, trace export, and call tree analysis for identifying performance bottlenecks.
🚀 Instruments Profiling helps you identify performance bottlenecks in macOS and iOS apps. Capture CPU time, analyze call stacks, and pinpoint slow functions using Apple's Time Profiler tool. Record traces via command line (xctrace) or the Instruments UI, then explore detailed call trees to understand where your app spends most of its time.
💡 Perfect for debugging startup lag, high CPU usage, or unresponsive UI. Use it to profile your app during real workloads—whether launching fresh or attaching to a running process. Export stack data for deeper analysis or share traces with your team.
✨ The CLI workflow (xctrace) is fast and scriptable, while the Instruments UI offers rich visualization. Key advantage: target the exact binary you built, avoiding LaunchServices confusion that profiles the wrong app version.
