MASTERING SWIFT - concurrency, parallelism, dispatch queue, operation queue

Hi there ...
This is the twenty-second chapter of the Mastering Swift Tutorial series.
In this chapter we are gonna talk about concurrency and parallelism.
When you’ve multiple tasks or threads that must be done as soon as possible. Concurrency is a good option. Because when a certain task has available time, we can use that time for doing another task. If your device processor has multiple cores which is more than one. Then each core can handle one different task/thread. In this case those tasks were handled simultaneously.

00:05 explaning concurrency and parallelism ?
04:18 gcd, dispatch queue
04:50 serial queue
12:28 concurrent queue
14:18 main queue
15:54 asyncAfter
16:33 operation queue
17:03 block operation
20:35 custom operation class
24:31 serial operation queue

You are gonna see lot of things about programming in a simplified tutorials.
