This definitely is a problem in Obj-C. Using GCD and callbacks is usually easier to understand than delegates and manual thread management, but it's still not great. I would love to see something like async/await in Obj-C. There are some great ideas on how to get something similar in this blogpost, but none that I would use in production code unfortunately: http://overooped.com/post/41803252527/methods-of-concurrency
