# PaperMarkupViewController

A view controller for interactively creating and showing markup.

## Declaration

```swift
@MainActor @objc @preconcurrency class PaperMarkupViewController
```

## Mentioned in

Integrating PaperKit into your app

## Overview

Overview Properties are observable, so to save markup changes to disk, iterate over the changes to markup. let markups = Observations.untilFinished { [weak paperViewController] in     if let markup = paperViewController?.markup {         return .next(markup)     }     return .finish } Task { [weak self] in     for await newMarkup in markups {         self?.save(model)     } }
