What do you mean by:
SwiftUI compiler fails to compile and just reports "I'm lost in the weeds", with no indication of what it was last working on, aside from a particular level in a multi-layered nested UI.
Have you raised any bugs about it? Perhaps if you explain - in a bug - exactly what the issue is, Apple's developers might be able to make improvements.
I raised a bug where I'd renamed a binding variable but forgotten to rename it in one place it was being used, and the compiler said it was unable to compile. Apple's developers fixed it, so when I forget to rename the use of the variable now it fails at that point, so I know where the issue is.
If you do the same, these bugs will be fixed. You'll be happier, other developers will be happier, Apple developers will be happier. It's the right thing to do :)
