Modern Concurrency: Getting Started

You’ve finished Part 1 of this course: great work!

To build your first asynchronous app, you took a quick look at some of the main features of Swift concurrency:

• Using async/await, you fetched a list of stock symbols from the course server.
• Then you got a never-ending AsyncSequence of price updates for selected stocks.
• You learned how to use the task view modifier to call an asynchronous method from a SwiftUI view,
• and how to run your view updates on the main thread with MainActor.
• You even got some practice with handling errors.

In Part 2 of this course, you’ll work on another app, SuperStorage. It’s a a cloud file storage app with three download plans:

• You’ll get a more detailed look at async/await, AsyncSequence and MainActor.
• You’ll use a top-level asynchronous Task to call an asynchronous method from a SwiftUI view.
• You’ll learn the async let syntax for grouping asynchronous tasks so they run at the same time.
• You’ll use a download stream iterator to process AsyncSequence bytes.
• You’ll get more practice canceling tasks.
• And you’ll even integrate a Combine publisher into your app.

See you soon!
