pdfkit

name: pdfkit description: Use when displaying, loading, annotating, searching, selecting, or bridging PDFKit documents into SwiftUI.

PDFKit

Review and write PDFKit code for correct document loading, view configuration, and annotation patterns.

Responsibility

Owns: PDFView, PDFDocument, PDFPage, PDFAnnotation, PDFThumbnailView, PDFSelection, PDFOutline, text search, page navigation, annotation creation, UIViewRepresentable wrapping.

Does NOT own: PDF generation from HTML (WebKit/print formatter), server-side PDF processing, Core Graphics PDF context drawing.

Core Principles

1. PDFView is UIKit. Wrap in UIViewRepresentable for SwiftUI. No native SwiftUI equivalent.
2. Load documents async. PDFDocument(url:) blocks — load on a background queue.
3. Configure after setting document. AutoScales, display mode, and other properties may reset when document changes.
4. Annotations modify the document. PDFAnnotation changes are in-memory until you call document.write(to:).
