Swift Concurrency Lesson 3 - Improving the User Experience

This is the 3rd of 6 videos in the Swift Concurrency series. In this video we are going to improve the user experience by doing two things. Whenever our app is fetching and loading data, we want to present a spinning ProgressView on top of our view to indicate that the data is loading.
If an error occurs, then we need to know about it so instead of printing the error to the console we want to present an alert to our users with that error information and ask them to contact us with that information.
