Demystifying Completion Handlers and Asynchronous Functions

In this video I am going to ty to demystify CompletionHandlers in Swift. We will be looking at asynchronous functions and the need to create a completion handler when we try to fetch data from a service that uses an asynchronous method. Along the way we will also look at the background and main thread and how we can let our users know that our app is busy fetching data. If you want to support my work, you can buy me a coffee :) https://ko-fi.com/stewartlynch ******* Download my StewartLynch YouTube Channel Application - Free ********** https://stewartlynch.gumroad.com/l/obsjz Table of Contents: 0:00 Introduction 4:03 The Asynchronous Function problem 8:00 Completion Handler 13:45 Working on a Background Thread issue 16:00 Cleaning up the the UI Starter Project Files: http://www.createchsol.com/StarterPro...
