You finished part one of the course, great work. To add features to Blabber, you created custom sequences with AsyncStream, both the pull driven and push driven varieties. You used a custom URL protocol to configure a URL session for asynchronous unit testing. You learned how to wrap a completion handler and a delegate method in a manual continuation. This mechanism helps you reuse your existing concurrency code so you can more easily adopt Swift concurrency. And you used another manual continuation to fix the timeout issue with asynchronous unit testing. In part two of this course, you'll work on two apps. The first, Sky, scans satellite imagery of the sky and analyzes it for signs of alien life. You'll learn how to use TaskGroup to create concurrency on the fly, reduce the possibility of data erases and that you safely process the results. The second app, EmojiArt, lets you browse an online catalog of digital emoji art. To verify that the digital art is authentic, the app reads the feed of current works of art from the server, verifies the digital signature of the images and only then displays them on screen. Working on this app will take you deep into the workings of the Actor and GlobalActor types. You'll learn how to use these to make your code thread safe. See you soon.
