I push json to a GitHub repo so It can be published with GitHub Pages. In order to do this, I use the GitHub API and I need a Fine-grained Personal Access Token for the repo. I have instructions and a testing app for this if anyone is interested.

Apple’s Foundation Models can do more than generate text if you give them tools. 🧰
In my latest video, I show how to connect them to real data sources and build custom tools in SwiftUI.

The Reluctant Traveller Season 3 finale on Apple TV is basically a love letter to my hometown, Vancouver. The market I still bike to, the mountain just 15 min away that I still ski, the bars I used to close down. It’s my city in every frame. Makes me proud to call this place home.
