Swift Robustness & AsyncLesson 38Free preview

Swift Concurrency

This lesson is part of Swift · All levels

Summary

This lesson discusses the Modern Competition feature in Swift using the async/await, Tasks, and Actors models. Launched on Swift 5.5, this model replaced the callback closure that was vulnerable to bug-prone 'callback hell'. The developers will learn how asynchronous functions work as well as the role of the Actor in preventing data race.

Key points

The asynchronous function is denoted by the keyword 'async' and is called 'await'
Removing the cramped callback pyramid
'Task' is used to launch asynchronous operations from a synchronous context
'actor' is a type of reference thread-safe that automatically isolates and protects its internal state from data race
