createDocument now queues and syncs like the other offline-capable writes, closing the gap deliberately left open earlier this session. Synthesizes a pending-<uuid> document (same placeholder scheme as pin/star/subscribe), caches it so it's immediately readable/openable, and queues the real create. On sync, the server's real document replaces the placeholder in the cache — no dead orphan entries. Editing that same still-unsynced document folds the edit into the pending create's payload instead of queuing a separate update, which would otherwise target the placeholder id and 404 forever once flushed. CreateDocumentRequest widened Encodable -> Codable for the queue round-trip. Known limitation: a reader still open on that exact document at the moment it syncs in the background keeps holding the stale placeholder id until navigated away and back. Narrow, not solved generally here. 3 new OutlineKit tests (57/57). Removed the now-unneeded offline restriction on the reader's New Document button/menu item.
Outpost
A native Apple ecosystem client for Outline — built for iOS, iPadOS, and macOS from a single SwiftUI codebase, aiming for full editing parity with Outline's web app, including realtime collaborative editing.
Why
Outline's web app is great, but there's no native Apple client with full editing parity. This project connects to a self-hosted Outline instance over its REST API and realtime collaboration socket to provide a proper native experience across the Apple ecosystem.
Status
Early development. See CLAUDE.md for the current architecture and phased build plan.
- Phase 1 — Auth, browse, search, REST-only editing
- Phase 2 — Realtime collaborative editing (Yjs/Hocuspocus)
- Phase 3 — Offline cache, tables, embeds, comments, macOS polish
Requirements
- Xcode 16+
- iOS 17+ / iPadOS 17+ / macOS 14+
- A self-hosted (or hosted) Outline instance with API access
They will be updated. These are old requirements.
Setup
- Clone the repo and open the
.xcodeprojin Xcode. - Generate a scoped API key on your Outline instance (Settings → API Keys).
- On first launch, enter your instance URL and API key — these are stored in Keychain, never in app config or source.
Architecture
See CLAUDE.md and docs/ARCHITECTURE.md for the full technical breakdown: REST layer, Yjs/Hocuspocus realtime sync via YSwift, and the ProseMirror-schema-to-native-editor mapping.
Disclaimer
This project is being built to solve a personal problem — I wanted a genuinely good native knowledge-base client for my own self-hosted Outline instance and none of the existing options fit. It's a personal-use tool first, not a polished product with support guarantees.
Parts of this codebase are AI-assisted (built with the help of AI coding tools). Treat that however you like — review, use, fork, or ignore the code accordingly. No warranty of quality, security, or fitness for any particular use is implied beyond what's stated in the license below.
