Concurrency Profiling — Instruments Workflows

Profile and optimize Swift async/await code using Instruments.

When to Use

✅ Use when:

• UI stutters during async operations
• Suspecting actor contention
• Tasks queued but not executing
• Main thread blocked during async work
• Need to visualize task execution flow

❌ Don't use when:

• Issue is pure CPU performance (use Time Profiler)
• Memory issues unrelated to concurrency (use Allocations)
• Haven't confirmed concurrency is the bottleneck
