Creating Interactive Widgets in iOS 14 Using SwiftUI

Widgets have transformed how users interact with their applications on iOS devices. With the introduction of WidgetKit in iOS 14, you can create delightful and engaging experiences right on the home screen. In this guide, we will explore how to create interactive widgets that respond to user actions, particularly focusing on using SwiftUI for this purpose.

The Problem: Interacting with Widgets

Imagine you want to create a medium widget similar to that of YouTube Music, where each item can be interacted with directly from the widget. The challenge arises in figuring out how your app can respond when a user taps on one of the items. If you're using SwiftUI for your widget but Swift for the main app, you may be uncertain about how to handle these interactions. Let’s dive into the solution!

The Solution: Implementing Interactivity with Link

One of the most straightforward ways to enable interactions within your SwiftUI widget is by using the Link view. The Link allows you to specify actions that should occur when the user taps on an element. Here’s a breakdown of how to integrate it into your widget.

Step 1: Modify Your Widget Code

You will need to replace the existing button functionality in your widget code with Link. Here’s how you can do that:
