You won't be able to do this, unfortunately. What I'd recommend doing is this:

// NSAppearance is a new class in the 10.9 SDK. New classes cannot be
forward-declared because
// they also require an @implementation, which would produce conflicting
linkage. Instead, just
// declare the necessary pieces of the interface as a protocol, and treat
objects of this type as id.
@protocol CrNSAppearance
- (NSString*)name;
@end

... but do that above line 247 so that you can do:

@interface NSView (MavericksSDK)
- (id<CrNSAppearance>)effectiveAppearance;
@end

Done.
