Was spricht für diesen Kurs?

Almsot all Apps consume data from web services, and therefore must use background threads for these lengthy operations.

Even though we provide a black box solution for concurrency in the iOS Networking with Swift course, it is important that you understand how concurrency works in iOS.

This knowledge is vital to deliver Apps that won't be rejected from the App Store and also provide a great user experience.
