Get an in depth look at what’s covered in our video tutorial course iOS Concurrency with GCD & Operations.
Learn the basics of concurrency and Grand Central Dispatch — serial and concurrent queues, synchronous and asynchronous dispatch.
Simple Use Cases
Learn how to wrap a synchronous function to make it asynchronous, and how to handle simple use cases — a chain of synchronous tasks and a collection of similar independent tasks.
Group Of Tasks
Learn how use GCD dispatch groups so that you can respond to the completion of a collection of GCD tasks.
In this video tutorial, you'll learn about what an Operation is, and how you can create and run Operations.
In this video tutorial you'll learn how to use OperationQueue to handle the scheduling and execution of Operations.
In this video tutorial, you'll learn how to use an Operation to wrap an asynchronous function such as a network call.
Learn how to use the results from one Operation in another and specify that the second Operation shouldn't be executed until the first has completed.
In this iOS concurrency video tutorial, you'll learn how to perform a cancellation of an Operation.
Operations In Practice
Pull together all the concurrency knowledge you've learned so far in this series to improve the scrolling performance of a table view in a realistic app.
Learn how to create thread-safe objects to prevent inconsistent state, and how to avoid other concurrency problems.
