- (void)foo:(float)i;
@end
void f(id i) {
[i foo:4.0f];
}
$ bin/clang -c test.m
test.m:9:6: error: 'foo:' is unavailable
[i foo:4.0f];
^
test.m:2:1: note: 'foo:' has been explicitly marked unavailable here
- (void)foo:(int)i __attribute__((unavailable));
^
This is incorrect, the float version of foo: is available. This is because the
warning only looks at the first overload.
If the order of Face1 and Face0 is swapped, the warning goes away.</pre>
