What’s the difference between these?
AFAICT NSURLErrorKey is used by general Cocoa code and NSURLErrorFailingURLErrorKey is used by Foundation networking. To understand this, you have to look at the history. NSURLErrorFailingURLErrorKey is the logical replacement for NSErrorFailingURLStringKey, which dates from the introduction of Foundation networking with Safari (rolled into the system with 10.2.x IIRC). Being in <Foundation/NSURLRError.h>, it only makes sense to use from Foundation networking code. NSURLErrorKey was introduced with 10.4, which is the start point for Foundation's long move to using NSURL for more than just networking.
