Network Manager Part 3 - ViewModel and Loading State

In the first two videos of this series, we built a solid Network Manager for fetching and decoding JSON while handling errors cleanly in SwiftUI. In this third part, we focus on improving our views by introducing a reusable, generic data view model that works across multiple screens. You will learn how to move networking logic out of SwiftUI views, manage loading state with progress indicators, and create a reusable loader view modifier. We also cover pull to refresh, task cancellation issues with refreshable, and how to avoid them safely. Finally, we generalize the view model so it can handle arrays, single objects, and custom JSONDecoder configuration such as ISO 8601 date decoding.
