Does that really matter that not many people use it? Apple's carve-out of Objective C from the broader C ecosystem spanned something like 25 years.
Sure, the 90's were a rough period for them, but I think a series of failed OS strategies and technical debt are more responsible for that than just what language they used.
You could argue that their ambitions re Swift scaling from scripting all the way to writing an entire OS might never grow substantially outside Apple, but there's also the teaching aspect to think about.
"Objective C without C" removes a whole class of problems people have in just getting code to run, and I'll bet it shapes their mind in how they think about what to be concerned about in their code v what's just noise.
