npx skills add dpearson2699/swift-ios-skills --skill pdfkit -a claude-codeWhat pdfkit does
The skill covers displaying and loading PDFs, moving between pages, searching document text, and extracting page content. It also describes annotations, thumbnails, PDF form filling, and wrapping PDFView for SwiftUI.
Its examples use PDFView, PDFDocument, PDFPage, PDFAnnotation, and PDFSelection. Documents can be loaded from a URL or Data, then edited and saved. Page indices start at zero; an invalid index can raise an exception, so validate it before accessing a page.
To use the framework, import PDFKit; the guide says no entitlements or Info.plist entries are needed. The system find interaction requires iOS/iPadOS 16 or later, so check the target version before relying on it.
What it helps with
- embed a PDF viewer in a Swift app
- search a document and jump to a match
- attach a highlight or text note to a page
- extract text from a PDF page
- reorder pages and save the document
Example prompts for the agent
- Show me how to display a PDF in my Swift app with PDFKit.
- Add text search to this PDF viewer and navigate to a match.
- Explain how to attach a note to a PDF page and save the document.
