Overview of this book

If you're looking to work and experiment with powerful iOS 14 features such as widgets and App Clips to create your own apps, this iOS programming guide is for you.

Passing restaurant data to the Restaurant Detail screen

In the example discussed in the previous section, the app clip will be launched when you scan an Apple App Clip code. This code can include details about a restaurant, such as the city where the restaurant is located and its ID.

To simulate receiving information from an Apple App Clip code, you'll add an associated domain to your app clip target, configure your Run scheme to simulate receiving a URL, add code to your app clip to parse the URL for restaurant data, and pass this data to the Restaurant Detail screen. Note that you'll need a paid Apple developer account to do this.
