Why would you assume Apple is working to reduce Obj-C verbosity? The language has been around for decades and they seem to be doing pretty well with it as-is.

The language may be decades old, but clearly Apple is continuing to advance the compiler to improve the language's syntax and verbosity without breaking the runtime.
Why do you assume that Apple isn't working on his language? They are heavily developing it!
