Oh, right, because it seems to need a static or global variable for the flag. I've always wondered why that was the case. Seems like any flag would do (like a member variable), and if that results in a second dispatch because it's a second flag, that's okay. In any case, thanks for all the clarification. > > Share and Enjoy > -- > Quinn "The Eskimo!" <http://www.apple.com/developer/> > Apple Developer Relations, Developer Technical Support, Core OS/Hardware > > > _______________________________________________ > swift-users mailing list > swift-users@swift.org > https://lists.swift.org/mailman/listinfo/swift-users -- Rick Mann rm...@latencyzero.com _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
