Ya I was considering a similar workflow last time I was steeped in SwiftUI. I don't dislike it that much actually, maybe just how slow the compile and error alerting is/was last time. I mainly found mac SwiftUI performance to be lacking, along with the transparency and documentation of the api. Swift itself is fine, and I give a xcode a lot of credit for somehow functioning as well as it does with so much accumulated functionality/complexity/bloat.

SwiftUI previews were... manageable but not great.
