FAQPage Schema

How do I add cross-platform markup and drawing annotations to my iOS and macOS app?▼

You can add cross-platform markup and drawing annotations by initializing PaperMarkupViewController with a suitable FeatureSet, then presenting it within your app's UI to enable interactive drawing, text, images, and shapes across iOS, iPadOS, macOS, and visionOS.

What is a unified framework for document annotation across Apple platforms?▼

A unified framework for document annotation across Apple platforms combines drawing and structured markup into a single interactive canvas, adapting to device capabilities via FeatureSet configuration to accelerate feature development for notes, screenshots, and editors.

Do I need Swift 6.3 and iOS 26 SDKs to implement PencilKit-style markup tools?▼

Yes, implementing PencilKit-style markup tools with this unified framework requires Swift 6.3 or later and the iOS 26+ or macOS 26+ SDKs to support the cross-platform annotation canvas.

Can I configure which annotation features are available for drawing, text, and images on iPadOS?▼

Yes, you can configure available annotation features on iPadOS by defining a FeatureSet when initializing the PaperMarkupViewController, allowing the markup canvas to adapt to specific app capabilities for drawing, text, images, and shapes.

What's the best way to build a multiplatform annotation canvas for visionOS, macOS, and iOS?▼

The best way to build a multiplatform annotation canvas is using a unified framework that provides a single PaperMarkupViewController, ensuring consistent drawing and markup tools across visionOS, macOS, and iOS without maintaining separate platform implementations.

Why use a unified markup toolkit instead of separate drawing implementations for each Apple platform?▼

Using a unified markup toolkit instead of separate drawing implementations solves integration complexity by providing a single canvas with consistent annotation tools across iOS, iPadOS, macOS, and visionOS, accelerating feature development for document markup.
