Great that we met again after around 7 minutes! Let’s start with async/await. In this article, I am explaining to you what is async/await, how and why do we use it, and also at the end I will share with you some read-more articles from well experienced people.
We got the opportunity to use async/await right after WWDC21. Just a quick information for those who does not know what is WWDC. It is happening once a year and we hear about updates for Swift, Xcode and etc. So this is kind of update for us (I felt myself as an app now 😄).
With this, we got rid of unnecessary closure usage. We have an asynchronous structure that is more readable and executes operations properly.
If you follow me, you know that I love to keep everything as simple as it is possible and explain it to make clear for everyone:
async: Indicates that a method or function is asynchronous. Using this allows you to suspend execution until an async method returns a result.
await: Indicates that your code can pause execution while waiting for an asynchronously declared method or function to return.
I hear you, I hear that you are asking some code examples. Here we go:
Since WWDC21, instead of this:
We use this:
