There are also a number of attributes like `@noescape` and `@discardableResult`, which aren't 100% consistent.

Right, but the catfight had a clear outcome:

1) keywords are conjoined
2) attributes are lower camel cased.
3) attributes should use “non” not “no”.  noescape should be nonescaping (and thus no camel bump).
