Summary
Wraps PKCanvasView, PKToolPicker, and PKDrawing for Apple Pencil input on iOS, iPadOS, and visionOS. Covers the full lifecycle: setting up a canvas with drawing policies (pencil-only, any-input, or default), managing the tool picker with custom ink types from pen and marker to the iOS 26 reed pen, serializing drawings to Data, and exporting to images. The content version compatibility section is the real value here. It maps version1 through version4 to specific ink sets and features, shows how to gate syncing with requiredContentVersion, and explicitly warns against silently overwriting drawings that require newer versions than a recipient can load. If you're building cross-device drawing features or annotation tools that sync, this handles the versioning headaches upfront.
