I am amazed how well it works. Yesterday I have spent a full day with a new macOS project with idea in my head. Spend half a day writing basic features, and after that opened the project in Zed to add features. Not very well documented things like AppKit + SwiftUI integration - no issues, and I mean I was getting about 500 new lines from my questions and was getting compilable code (and working). A few times after review I modified a few things to make it compilable/or better. But still.
And I had one interesting problem with objc/swift and javascript integration - and Zed AI delivered some masterpiece in JavaScript, that is definitely outside my knowledge.
This technology is definitely going to change how we program now.
(not the one you asked, but can chime in with some info)
This was a long time ago, but the way I did it was to use XcodeGen (1) and a simple Makefile. I have an example repo here (2) but it was before Swift Package Manager (using Carthage instead). If I remember correctly XcodeGen has support for Swift Package Manager now.
On top of that I was coding in VS Code at the time, and just ran `make run` in the terminal pane when I wanted to run the app.
Now, with SwiftUI, I'm not sure how it would be to not use Xcode. But personally, I've never really vibed with Xcode, and very much prefer using Zed...
