Hi, This patch allows trailing commas in protocol lists. This is useful when conditionally conforming to protocols. For example:
@inteface MyView : UIView <
UITableViewDelegate,
#ifdef IN_APP_EXTENSION
UIGestureRecognizerDelegate,
#endif
#ifdef OPTIONAL_FEATURE
UITextFieldDelegate,
#endif
>
@end
Without this patch, there's no clean way to write that because the
protocol list is not allowed to have a trailing comma. (You could use
JavaScript-style leading commas, but that’s not common in C-based
languages.) With this patch, the trailing comma is simply ignored. It’s
similar to how it’s ignored in Objective-C array and dictionary literals.
