OwnPost

OwnPost is a SwiftUI app for writing notes in Markdown, publishing canonical posts to Ghost, and syndicating to Mastodon and Bluesky (POSSE workflow).

Features

• Markdown editing and preview
• Local persistence with SwiftData
• Publishing to Ghost Admin API
• Syndication to Mastodon and Bluesky
• Optional on-device AI helpers (proofreading and alt text)
• iOS and macOS targets

Tech Stack

• Swift 6.2
• SwiftUI + Observation
• SwiftData
• swift-markdown for Markdown parsing/export
• FoundationModels (on supported devices)

Requirements

• Xcode 26+
• iOS 26 / macOS 26 SDK
• Swift 6.2 toolchain
• xcodegen (if you want to regenerate the Xcode project from project.yml)

Getting Started

1) Clone and enter the repo

git clone https://github.com/wpowiertowski/ownpost.app.git
cd ownpost.app

2) Build with Swift Package Manager

swift build --scratch-path .build

3) Generate Xcode project (optional)

xcodegen generate
open OwnPost.xcodeproj

If you already have a generated project, you can open it directly in Xcode and run on iOS Simulator or macOS.

Configuration

Publishing credentials are configured inside the app settings:

• Ghost: Admin API URL + Admin API key ({id}:{secret})
• Mastodon: instance URL + OAuth flow
• Bluesky: handle/email + app password

Credentials are stored via Keychain services in OwnPost/Services/Keychain/KeychainManager.swift.
