It's a pointer to a struct objc_selector.
Jump to definition in XCode is helpful for these things.
You want %p to print the pointer value or consider using sel_getName ().

What's the type of a selector? I gather it's a SEL -- but what's a
SEL, as far as trying to print one using NSLog is concerned?
This attempt to find out compiles, but craps out when I try to run
it, in an asm called objc_msgSend_rtp:
- (void)foo {
NSLog(@"%@", @selector(foo));
} //end foo
The Run log sez:
