PaperKit

Beta-sensitive. PaperKit is new in iOS/iPadOS 26, macOS 26, and visionOS 26. API surface may change. Verify details against current Apple documentation before shipping.

PaperKit provides a unified markup experience — the same framework powering markup in Notes, Screenshots, QuickLook, and Journal. It combines PencilKit drawing with structured markup elements (shapes, text boxes, images, lines) in a single canvas managed by PaperMarkupViewController. Requires Swift 6.3 and the iOS 26+ SDK.
