FWIW, I'm getting this on Xcode 16.4 with no Swift Package Manager. The error alert will popup in groups of 5 or 6. All the buttons just close the alert and lead to another one.

@DTS Engineer Is there any update or hints to this? We're back to 1970's debugging here which is time consuming for such a large team. swift-healthcheck is showing Missing Swift module or Clang module found for all our (Cocoapods) dependencies. Even attempted to use -add_ast_path manually, but the problem there is how to determine that path. All guesses have failed so far. I'm not clear why I would have to manually set those in Xcode 16 either. The code block option seems to suffering from an offset issue here too, btw. Had to fix the back ticks in the first paragraph. Not sure if @DTS Engineer is working either?
