  Async Algorithms for Swift

  

Last weekend, I started reading up on Swift Concurrency through the use of async-await, actors, etc... I really liked what I read and thought of converting my current code to use these new Swift Concurrency tools and ditch the GCD. I used continuation to convert all methods with completion handlers from the Device class to async throw methods and turned Device into an actor in order to protect some members from race conditions. Once more, I am faced with the issue of calling the async methods of the Device actor one by one (waiting for each ones completion before starting the next one). I spent a lot of time thinking on how to do this and came across a number of useful references such as this one and this one. I tried to think of ways of implementing such a channel in my controller class, to guarantee sequential execution of different tasks that require the underlying library, but I'm facing a few issues with this approach:
