Bookmarked “I Shipped a macOS App Built Entirely by Claude Code”

I recently shipped Context, a native macOS app for debugging MCP servers. The goal was to build a useful developer tool that feels at home on the platform, powered by Apple’s SwiftUI framework. I’ve been building software for the Mac since 2008, but this time was different: Context was almost 100% built by Claude Code. There is still skill and iteration involved in helping Claude build software, but of the 20,000 lines of code in this project, I estimate that I wrote less than 1,000 lines by hand.

Indragie shipped a native macOS app with Claude Code writing 95% of the code. Haven’t dug into the full post yet, but Simon Willison pulled out the key bits – Claude nails SwiftUI but gets tripped up by Swift’s newer concurrency stuff.
