Mastering WidgetKit in SwiftUI 4, iOS 16 with Dynamic Island - Widget Deep Link Through OpenURL

This video tutorial guides viewers through modifying an app to handle deep links using the Open URL Modifier. It explains how to validate URLs with guard statements, update the selected country based on URL path components, and test the deep link functionality. The tutorial also explores the structure of path components in URLs and concludes with a preview of the next section on Widget Git.

What is the primary purpose of adding an Open URL Modifier in the Exchange Rate app?
