The problem is that the requirement is self-contradictory: "synchronous" means wait, and "without impacting performance" means don't wait. While the real requirement is probably more like "do certain things while the bg task is running, then do something else when it completes". To really answer the question, you have to break down what needs to be while the bg task is running and what has to be done after, then categorize those into the type of tasks, such as whether or not they interact with UI and thus have to run on the main thread, and so on. It sounds to me like your friend is trying to avoid that level of analysis with a hand-wavy magic solution that both waits and does not wait. Sorry, but it's time to open that box and see if the damned cat is dead or not ;-) -- Scott Ribe scott_r...@elevated-dev.com http://www.elevated-dev.com/ https://www.linkedin.com/in/scottribe/ (303) 722-0567 voice _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
