GPTs for Devs
38 custom GPTs trained on Apple docs for Swift developers, reaching 100K users in the first week and adoption from Apple's Swift team.
Overview
A directory site linking to 38 framework GPTs, plus 16 MDX articles. Promotion on r/swift created a sharp launch spike and adoption by Apple's Swift team.
Problem
ChatGPT hallucinated on Apple APIs. Swift developers needed framework-specific help grounded in official docs.
Solution
Scraped Apple's documentation into structured knowledge bases and created framework-specific GPTs with RAG grounding.
Lessons learned
- Timing beats polish when a platform window opens.
- Reddit works when the launch solves a real problem.
- RAG quality depends on source quality.
