I’ve talked a bunch of smack about this Composer model in my head for a while, but I was having an ugly performance issue with flatlist and flashlist that I spent weeks on trying to debug; I kept getting peculiar jank when using tabs on return to any screen with a list (any kind of list). Nothing I was doing was working; nothing Claude or Codex was doing worked. And it turned out it was newArchEnabled being set to True. That instantly solved it after rebuilding, and now I am plucking out all my debugging from the codebase. Composer figured this out in ONE PROMPT, by the way. But I will say, I had been documenting thoroughly every thing I had attempted and that Claude and Codex had attempted in a markdown file, which Claude and Codex had been working with to try figuring out what it could be, so Composer had the same context the other models had, and Composer still solved it.
Just came to say kudos, and thanks. If you’re documenting your debugging along the way, I guess I suggest to try giving Composer a try.
