What prevented you from finding the CFGetTypeID function?

Because they already documented the general case:
- [NSObject isKindOfClass:]

and

- [NSbject respondsToSelector:]

usually, one writes this as:

void DictRecurse(NSDictionary *dict) {
NSEnumerator *keys = [dict keyEnumerator];
id key;
while(nil != (key = [keys nextObject])){
id value = [dict objectForKey:key];
if ([id respondsToSelector:@selector(objectForKey:)]) {
DictRecurse(id);
}
}
}
