16. Connecting Home Page UI With Backend API | Swift 5, XCode 12
In this video, we connect the user interface for the home page with our backend.
We start by implementing the request function in the Network Service, then make the call when the app is first launched.
We also install a dependency called ProgressHUD to help us represent a loading state for when the request is processing.
Finally, do some debugging to fix an issue where category names were not showing up.
