I dunno. A different domain would be like if I called my new bluegrass band, Uikit.
This name does sort of confuse. Although I don't know how more generic you can get then, "User Interface Kit", although the capitalization of Uikit is a little awkward.
Not that generic – Apple uses "kit" as a suffix for most of their frameworks, and I don't know any other large frameworks that do that (could be wrong on this, of course, but it does seem an "Apple thing" at this point).
