# Using Xcode Instruments to optimize Swift Concurrency Code

**[SwiftLee](https://daily.dev/sources/avanderlee)** · 4 min read · 0 upvotes · 0 comments

## Summary

A guide on using Xcode Instruments to analyze and optimize Swift Concurrency code. Covers the difference between Instruments templates and individual instruments, focusing on the Swift Concurrency template which includes Swift Tasks, Swift Actors, Time Profiler, and Hangs instruments. Emphasizes the importance of profiling at scale rather than relying on debug-time performance, and warns that agentic/AI-generated code may introduce performance regressions.
