GPT-5.6 vs Fable 5: 4 UIs, Judged Blind, 1 Winner



Hey Reader,

I didn't sleep much last night. I was up pushing Sol to fix things that GPT-5.5 couldn't.

I had them work on SwiftUI for an iPhone app today.

This is the brains of my timer app, and it's shared across iOS and macOS. The MVP worked last week, but it wasn't reliable until I added AlarmKit. That allows timers to persist even if the app is force-quit or the iPhone is locked (just like Apple's system alarms). That was my biggest blocker, and now that it's in,...
