create simple swiftUI app with pencilkit

To create a simple SwiftUI app with PencilKit, you can leverage the advancements and features introduced in the session titled "Squeeze the most out of Apple Pencil" from WWDC 2024. PencilKit provides an easy way to integrate a rich drawing experience into your app, and with the new Apple Pencil Pro, you can enhance this experience further.

Here's a basic outline to get you started:

1. Set Up PencilKit: Use the PKCanvasView to create a drawing canvas. This view will handle the drawing interactions with the Apple Pencil.

2. Tool Picker Integration: Utilize the PKToolPicker to provide users with a variety of drawing tools. You can configure the tool picker to include custom tools specific to your app's needs.

3. Custom Tools: You can build custom tools into the tool picker. For example, you might want to add a custom stamp tool or a shape picker.

4. Apple Pencil Pro Features: Take advantage of the new features like the squeeze gesture to quickly switch tools or show the tool picker. You can also use the barrel roll angle to control the angle of strokes, providing a more expressive drawing experience.

5. SwiftUI Integration: There are new SwiftUI APIs available to integrate PencilKit into your SwiftUI app seamlessly.

For a detailed demonstration and code examples, you can refer to the session Squeeze the most out of Apple Pencil (08:47) which covers Apple Pencil Pro features and APIs.

By following these steps and utilizing the resources from the session, you can create a simple yet powerful drawing app using SwiftUI and PencilKit.
