Same here! That’s precisely why I experienced those crashes. It attempted to automatically apply those model changes without knowing how (because of missing migration files), leading to conflicts.

I got some crashes as well but in my case I learned it was partly due to how SwiftData handles migrations in the Simulator and Xcode preview, when changing the properties of a model.

Setting up a simple site with Vercel is also quite easy. You can automatically deploy every time you push something to your repo e.g. to the main branch.
