Mastering WidgetKit in SwiftUI 4, iOS 16 with Dynamic Island - Expense Category

In this video, the instructor guides viewers through creating an expense category in a widget group. The process involves adding a new file to represent a custom enum, which maps to a category in the intent definition file. The enum is defined as an int type, starting from index one due to a default 'unknown' case. Each enum value is given a description using a switch statement. The video concludes by preparing for the next step, which involves creating a timeline entry for the widget.
