Seeking advice on building a multiplatform PDF viewer app

Hi everyone,

I’m planning to develop a cross-platform PDF viewer app for iOS and macOS that will read PDFs from local storage and cloud services (Google Drive, iCloud, WorkDrive, etc.). The app should be read-only and display both the PDF content and its metadata (author, title, creation date, etc.).

Key Features:

1. View PDFs: Local and remote (cloud storage integration).
2. Display metadata: Title, author, page count, etc.
3. Cloud integration: Google Drive, iCloud, Zoho WorkDrive, etc.
4. Read-only mode: No editing features, just viewing.

Questions:

1. Xcode Template: Should I use the Document App or Generic App template for this?
2. PDF Metadata: Any built-in libraries for extracting PDF metadata in a read-only app?
3. Performance: Any advice or documentation on handling large PDFs or cloud fetching efficiently?

Thanks in advance for any advice or resources!
