Extended Description

The result of +alloc should be inferred to be an instance of the receiving "self" class here, but is apparently just being typed as "id". This cause clang to think the -initWithContentsOfFile: and -initWithContentsOfURL: are possibly the deprecated methods in Foundation.

I think this got fixed at some point. Unless I'm doing something wrong, the attached test case no longer repros (at least not against the 10.9 SDK).

Can someone with Radar access check rdar://problem/10582691 and rdar://problem/10678345?

Radar rdar://problem/10582691 is still unresolved.
