Hello, it seems this broke building some iOS programs.
$ cat test.m
# define UI_APPEARANCE_SELECTOR
__attribute__((annotate("ui_appearance_selector")))
@class UIColor;
@interface Test
@property(null_resettable, nonatomic, strong) UIColor *onTintColor
UI_APPEARANCE_SELECTOR;
@end
@implementation Test
- (void)setOnTintColor:(nullable UIColor *)onTintColor {
}
@end
$ out/gn/bin/clang -c test.m -Wno-objc-root-class
test.m:10:44: error: nullability specifier 'nullable' conflicts with
existing specifier '_Null_unspecified'
- (void)setOnTintColor:(nullable UIColor *)onTintColor {
^
1 error generated.
Before this change, that compiled fine. Surprisingly, it still builds fine
if UI_APPEARANCE_SELECTOR is replaced by
`__attribute__((annotate("ui_appearance_selector")))` in the source code,
even though both lead to the same -E output.
