Swift - Objective-C load class method?

In Objective-C, NSObject had a class method called load that gets called when the class is loaded for the first time. What is the equivalent in Swift?

@implementation MyClass

+ (void)load
{
   [self registerClass];
}

@end

Prior to Swift 1.2:

override class func load() {
   NSLog("load");
}

EDIT:

As of Swift 1.2 you can no longer override the load method. Look into the method initialize instead, it behaves different than load though, it get's called the first time the class is being referenced somewhere rather than on application initial load
