Hadron for iOS

Native iOS client for the Hadron knowledge-memory platform. v1 scope: sign in with your Hadron account and search across your memories.

Layout

• Hadron/ — the app target (SwiftUI, iOS 17+).
• HadronKit/ — shared Swift package with the Hadron client stack (OAuth 2.1 PKCE sign-in, Keychain storage, GraphQL client). Also consumed by hadron-macapp via a local path dependency.
• project.yml — XcodeGen spec; the .xcodeproj is generated and gitignored.

Building

brew install xcodegen        # once
xcodegen generate
xcodebuild -project HadronIOS.xcodeproj -scheme Hadron \
  -destination 'platform=iOS Simulator,name=iPhone 16 Pro' build

Or open HadronIOS.xcodeproj in Xcode and run.

Auth

The app signs in via Hadron's OAuth 2.1 authorization server (srv.hadronmemory.com): discovery → dynamic client registration (client id cached in the Keychain) → PKCE S256 authorization in an ASWebAuthenticationSession (provider choice: Apple, GitHub, or Google) → token exchange. The issued hdr_user_* key is a long-lived bearer stored in the Keychain; there is no refresh token — a 401 drops the app back to signed-out.
