What build command are you using? I’m not seeing any warnings with this code,
compiled with clang -x objective-c -framework AppKit -Wunguarded-availability
-mmacosx-version-min=10.9 - :
#import <AppKit/AppKit.h>
int main() {
NSPrintInfo *info;
if (@available(macOS 10.9, *)) {
info.orientation = NSPaperOrientationPortrait;
} else {
info.orientation = NSPortraitOrientation;
}
}
Regardless, if you really need a fix, you should be able to cast through
NSInteger, instead of NSPrintingOperation, as a fallback.
