Integrate Apple Pencil drawing in SwiftUI by implementing PKCanvasView to capture touch input, PKToolPicker for tool selection, and PKDrawing for ink data serialization. This enables canvas drawing, document annotation, and signature capture.

The best way to add signature capture on iPadOS is using PencilKit's PKCanvasView to capture Apple Pencil input and PKDrawing to serialize the signature data for persistent storage within your application.

PencilKit supports ink serialization through the PKDrawing class, allowing you to serialize and deserialize drawing data for persistence and sharing across iOS, iPadOS, and visionOS platforms.

You can use PKCanvasView to build document annotation features by capturing Apple Pencil and touch input directly on the canvas, enabling users to draw diagrams and markup files with a familiar tool interface.

Display a drawing tool picker for Apple Pencil input by implementing the PKToolPicker component in your PencilKit canvas view, providing users with standard selection options for various drawing tools.

PencilKit canvas management and data persistence using PKCanvasView, PKToolPicker, and PKDrawing requires Swift 6.2 and iOS 26+, extending support to iPadOS and visionOS platforms.
