There's no problem adding protocols (we can just the version macros to have the protocol for recent OSX versions and no protocol when building for older versions) but ... this one uses the @optional keyword.

That means having it be compiler specific ... we have different versions of gcc and different versions of clang supporting different language additions :-(

That really means we would need to make use of this protocol conditional upon compiler features tested at build-time ... so I think this is really conditional upon someone designing/implementing a mechanism to make things used in headers conditonal upon the compiler being used.

This is a change request, not a bug. It is very important, however, that we consider this.

Woops sorry, pressed return by accident...

Apple defines NSStreamDelegate as a formal protocol now. This causes valid foundation code not to compile.

Steps to reproduce:
1) create a new class @interface A : NSObject<NSStreamDelegate> @end
2) compile the code

Expected results:
Compilation success

Actual results:
Failure due to the NSStreamDelegate protocol not being defined

Apple's definition:

@protocol NSStreamDelegate <NSObject>
- (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode;
