## Setup

PDFKit requires no entitlements or Info.plist entries.

```swift
import PDFKit
```

| PDFKit framework | iOS/iPadOS/tvOS 11+, Mac Catalyst 13.1+, macOS 10.4+, visionOS 1.0+ |
| Find interaction and page overlays | iOS/iPadOS 16+ |

## Displaying PDFs

`PDFView` renders PDF content and handles zoom, scrolling, text selection, and page navigation.

```swift
import PDFKit
import UIKit

class PDFViewController: UIViewController {
    let pdfView = PDFView()

    override func viewDidLoad() {
        super.viewDidLoad()
        pdfView.frame = view.bounds
        pdfView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        view.addSubview(pdfView)

        pdfView.autoScales = true
        pdfView.displayMode = .singlePageContinuous
        pdfView.displayDirection = .vertical

        if let url = Bundle.main.url(forResource: "sample", withExtension: "pdf") {
            pdfView.document = PDFDocument(url: url)
        }
    }
}
```

### Display Modes

| Mode | Behavior |
|---|---|
| `.singlePage` | One page at a time |
| `.singlePageContinuous` | Pages stacked vertically, scrollable |
| `.twoUp` | Two pages side by side |
| `.twoUpContinuous` | Two-up with continuous scrolling |

### Scaling and Appearance

```swift
pdfView.autoScales = true
pdfView.minScaleFactor = pdfView.scaleFactorForSizeToFit
pdfView.maxScaleFactor = 4.0
