Yes — two, in fact. If you have a Foundation-type framework (e.g. from Cocoa, Cocoa Touch or GNUstep), you can use the NSClassFromString() function, which is precisely the same as your func. If you do not want to depend on a framework, there's a similar runtime function, objc_getClass(), that takes a const char* and returns the named class (or nil if none is found).
