Profile and optimize iOS apps with Instruments, memory management, and rendering techniques.

How to use

Copy the installation command and review the source package before installing it in your own agent environment.
Check the source document for required tools, credentials and supported hosts.
Describe your input and desired deliverable; review the output against the source material.

Profile with Instruments — Regularly use Allocations and Leaks to detect memory issues. Use Time Profiler for CPU stalls.
Reuse cells — Always use dequeueReusableCell and keep cellForRowAt lightweight.
Cache images — Use SDWebImage or Kingfisher for remote assets. AsyncImage lacks caching for lists.
Offload to background — Move parsing, encryption, and heavy computation off Main thread using GCD or Tasks.
Enable strict warnings — Set SWIFT_TREAT_WARNINGS_AS_ERRORS in Release builds.
Run static analysis — Use Xcode's "Analyze" (Product > Analyze) to catch logic errors.

No Main-thread Processing: Offload parsing/processing to background using Task.detached or GCD
No Manual Cache Clears: Let system handle low-memory via applicationDidReceiveMemoryWarning
No Retain Cycles: Use Leaks instrument frequently during development
