That’s useful information for the developer to have, and if the compiler doesn’t know them in some way, you can be assured Xcode’s autocomplete won’t see them.

The community and the core team just finished bikeshedding a huge change to how API's are imported and how labels are used and how important they are and then we do this?

I agree that this proposal should be re-evaluated. Apple stressed readability at WWDC this year, and taking away the argument labels takes away readability. Also, I think it fails these two important tests:

No. It is not a major problem, and it can easily be worked around. Also, this change could break some source code, requiring changes to existing code.

No. As stated above, it decreases code readability, which was stressed at WWDC.
