LLMs/AGENTS for legacy codebases

Hello there everyone.

I've got numerous support projects using old school development. Things from Objective-C to RxSwift and UIKit.

I've tried the LLM/Agents and they just destroy the codebase over time, so I have given up.

The final straw was trying to get it to fix a POSTCODE validation issue which was using some novel ways to provide validation in place using RxSwift.

Has anyone had any luck with these LLMs on Legacy codebases? Would love to hear tips.

Hello @Peer123123123123,

Xcode's Coding Intelligence supports all languages, so you can use it in any source file Xcode opens. That said, quality and feature coverage vary by language.

If a specific language is important to your workflow, please file an enhancement request with Feedback Assistant and add a description. Reply with the feedback number once complete, I will make sure this report is seen by the relevant engineering team.

Keep me updated, i'm curious how this works for your use case.
