For example: usage of named enums. In C, all enums (or #defines) all
live within the name namespace, with a prefix serving as the
disambiguating "namespace", and all are implicitly convertible to each
other. In many places, the bindings use named enums instead, which
provides the advantage of strong typing - if a function accepts a
parameter of a certain enum, you cannot accidentally pass a member of
another enum.
Apple exposes their C/Objective-C enums in Swift without the usual
prefix, example:
Objective-C:
enum {
NSOrderedAscending = -1,
NSOrderedSame,
NSOrderedDescending
};
typedef NSInteger NSComparisonResult;
Swift:
enum NSComparisonResult : Int {
case OrderedAscending
case OrderedSame
case OrderedDescending
}
