Double clicking on a brace helps to find its counterpart really quickly and reliably. Nice little Xcode feature that would simplify the process a little bit. Really nice job with a satisfactory result, guys!

Thanks!

Hi Caio, Mike, and Bogdan, Thank you very much for sharing this video here on youtube. It really was a pyramid of Doom but you showed us two ways to make it better. Thanks. I have one question, though: How did you come to know about 'withCheckedThrowingContinuation' and that it can be used here?

[@EssentialDeveloper]

Glad you liked it! This method was introduced along with async/await - it was presented in a WWDC session. You can learn more about it here: developer.apple.com/documentation/swift/withcheckedthrowingcontinuation(function:_:)

Can we use dispatch work items to solve this problem as well🤔

[@EssentialDeveloper]

Hi! You could but we don't think it wouldn't make the code easier to read.
