Build simple app

To build a simple app, you can follow several approaches presented in different sessions at WWDC. Here are some steps and resources that might help you get started:

1. Using App Intents:

   • You can add features like shortcuts actions, home screen widgets, control center controls, and app shortcuts for Spotlight and Siri using the App Intents framework. This allows you to share a lot of code between these features.
   • For a detailed guide, you can refer to the session Bring your app’s core features to users with App Intents.

2. Swift and SwiftUI:

   • If you are interested in using Swift, you can start by building a simple REST API or a basic Swift application. The session What’s new in Swift covers building a Swift package and deploying it.
   • For SwiftUI, you can refer to the session Evolve your document launch experience which provides a guide on getting started with SwiftUI.

3. Embedded Swift:

   • If you are interested in embedded systems, you can start with a basic Swift application running on an embedded device. The session Go small with Embedded Swift provides a step-by-step guide on how to get started.

4. Adding Personality to Your App:

   • To make your app more engaging, consider defining its voice and personality. The session Add personality to your app through UX writing offers exercises to help you define your app's voice and write a welcome screen.

5. Integrating with Siri:

   • You can also integrate your app with Siri to perform actions. The session Bring your app to Siri shows how to integrate an app with Siri and provides sample code.

6. Using Generative Tools:

   • For prototyping and quickly visualizing ideas, you can use Swiftassist. The session Platforms State of the Union demonstrates how Swiftassist can help in creating structs, adding images, and even playing sounds.

Here is a list of relevant sessions mentioned:

1. Bring your app’s core features to users with App Intents
2. Add personality to your app through UX writing
3. What’s new in Swift
4. Go small with Embedded Swift
5. Evolve your document launch experience
6. Bring your app to Siri
7. Platforms State of the Union

These resources should provide a comprehensive guide to building a simple app using various tools and frameworks presented at WWDC.
