Hi, I'm Jerry PM
I am an iOS engineer and I have written about Swift and Xcode here since 2018. These days most of my writing is about Claude Code and AI coding agents: how to configure them, where they help on a real iOS codebase, and where they fail. Guides on this site show the actual configs and commands. When something was not tested, the article says so. Between shipping apps I build small products (agent kits, a Figma-to-HTML extension, templates) and sell them on Gumroad and Etsy.
