Interesting example. My app has dozens of new warnings in Xcode 7 due to the
above. Hopefully this is not yet working as intended. Consider:
clang -Weverything -fsyntax-only ~/test.m
--------------
#import <AppKit/AppKit.h>
int main(void)
{
(void)[NSApp delegate];
return 0;
}
--------------
it gives:
/Users/sean/test.m:5:8: warning: multiple methods named 'delegate' found
[-Wstrict-selector-match]
(void)[NSApp delegate];
^~~~~~~~~~~~~~~~
Same if you use "[NSApplication sharedApplication]" instead of "NSApp".
(See rdar://21306753 which is really just rdar://6845498 still unfixed.)
Cheers,
