 5Star Interview Question on iOS Concurrency : NSOperation and Dispatch Queues Concurrency is always considered a monster of a subject in iOS development. It can be considered a dangerous area that many developers try their best to avoid. Rumor has it that multithreaded code should be avoided as much as you can. I agree with you that concurrency can be dangerous so if you don’t understand it very well. It is only dangerous because of the unknown. Think of how many dangerous actions or activities that people do in their life, many right? But once they master it, it becomes a piece of cake.
