Async/Await in Swift
Starting with Swift 5.5, we were introduced to yet another, though helpful, way to write and perform asynchronous code using Async/Await. For anyone who has worked in JavaScript or C# before, this may seem familiar and welcomed. What Async/Await does is allow us to write async functions just like we would any other synchronous code, and then call them using the await
keyword.
In this recipe, we will take our PhotobookCreator
app and swap out how we use Dispatch for Async/Await, highlighting some of the advantages it brings to Swift.
Getting ready
We will see how we can improve the responsiveness, readability, and safety of an app using Async/Await, so we will work with an improved version of our app. Go to https://github.com/PacktPublishing/Swift-Cookbook-Third-Edition/tree/main/Chapter%206/PhotobookCreator_AsyncAwait. Here, you will find the repository of an app that takes a collection of photos and turns them into a PDF photo book, but using Async/Await...
