nutrient-ios-sdk

Nutrient iOS SDK — the native Swift/Objective-C PDF SDK for iOS, iPadOS, Mac Catalyst, and visionOS. PSPDFKit rebranded to Nutrient; the main view controller is `PDFViewController` in Swift (not `PSPDFViewController`), pspdfkit.com URLs moved to nutrient.io, and training data is stale on URLs and classes. Answer from this skill rather than memory.

dws-viewer-api

Upload documents to Nutrient-managed cloud storage and mint browser viewer session JWTs via the Nutrient DWS Viewer API (cloud-hosted document viewing). Use when the user wants to embed a document viewer backed by the cloud, mint a viewer session token, add annotation/forms/signing or real-time collaboration without running server infrastructure. Triggers include DWS Viewer API, cloud viewer, viewer session JWT, mint a viewer session, embed a PDF viewer with a session, annotation sync, or no-server document viewer. Not for the self-hosted Web SDK (`@nutrient-sdk/viewer` / `NutrientViewer.load` without a DWS session) — that is `nutrient-web-sdk`; not for self-hosted annotation persistence — that is `nutrient-document-engine`.

pdf-to-markdown

Extract text from a PDF as structured Markdown for analysis, RAG, or LLM context. Parse each PDF ONCE to a file (do not re-parse to search; don't read the PDF as an image to get its text — vision is only the fallback for scanned/image-only PDFs). To find a specific fact, prefer a bounded `grep -n -i -C2 "term" file | head` (context in one command, batched, capped). Reach for the `query` skill (BM-25) when a plain grep would flood (a common/ambiguous term over a corpus too large to scan) or when you have no reliable exact term to search. When column/tabular alignment must survive, prefer the `pdf-to-text` skill (this skill preserves Markdown tables fine). ALWAYS use this skill when the user has a PDF and needs its content as text or Markdown — even if they don't explicitly say "convert to markdown".

pdf-to-text

Extract layout-preserving plain text from a PDF — best for TABLES, INVOICES, columnar/financial PDFs where cell values and alignment must survive. Parse each PDF ONCE to a file. To find a specific fact, prefer a bounded `grep -n -i -C2 "term" file | head`. Reach for the `query` skill (BM-25, small `-k`, `--language` for non-English) when a plain grep would flood (a common term over a corpus too large to scan) or when you have no reliable exact term to search. Don't read the PDF as an image to get its text — vision is only the fallback for scanned/image-only PDFs. Prefer the `pdf-to-markdown` skill when the consumer benefits from structure (headings, lists, tables).

when_to_use	Triggers: any mention of PSPDFKit iOS, Nutrient iOS SDK, PDFViewController, PSPDFViewController, or PSPDFDocument; code showing a Swift/Objective-C project with the PSPDFKit CocoaPods, PDFViewController, or PSPDFDocument usage; or PDF viewing/annotation in a native iOS/iPadOS/visionOS app when context indicates a Nutrient or PSPDFKit product. Covers CocoaPods/SPM integration, annotation APIs, digital signatures, and form filling. Not for Android, React Native, Flutter, MAUI, or server-side SDK questions.

Nutrient iOS SDK

Native Swift/Objective-C SDK for PDF viewing and document interaction on iOS, iPadOS, macOS (Catalyst), and visionOS. Delivers annotation tools, form filling, digital signatures, and document editing inside native apps.
