Should I fix Xcode 5 'Semantic issue: undeclared selector'?

Question

I\'m trying to upgrade my app with Xcode5 but encountered a number of \'Semantic issues\' in a third party library (being MagicalRecord). The quickest way to \'fix\' this mi

Answer 1

You just need to declare a class or protocol that contains the selector. For example:

//  DeliveryTimeComparison.h
#import 

@protocol DeliveryTimeComparison 

- (void)compareByDeliveryTime:(id)otherTime;

@end

And then simply #import "DeliveryTimeComparison.h" in any class where you plan to use @selector(compareByDeliveryTime:).

Or alternatively, just import the class header for any object that contains a "compareByDeliveryTime:" method.
