I built an iOS sewing-pattern app in two days using AI

When Apple released the Xcode 26.3 developer preview with enhanced AI integration, I needed a new project. My wife suggested a sewing pattern manager to help track large stashes of paper and digital patterns, and by combining a tightly integrated AI assistant with voice dictation I built a powerful iOS app with machine learning capabilities in under two days.

The app resembled my earlier filament manager in using photography and NFC tags to track physical items, but sewing patterns carry many more attributes. The potential market is far larger too: crafty sewists number around 30 million in the US and Canada, according to the Crafting Industry Alliance.

I started by copying the filament project, renaming it for sewing patterns, and working with Xcode and Claude Agent. Xcode 26.1 had been unusable for vibe coding, and I previously used Claude Code in the terminal to build iPhone, Mac, and Watch apps.
