Create a native macOS SwiftUI app from a working template (Swift package, SwiftData, build script, icon script, snapshot mode, git), with no Xcode GUI. Use when the user wants to start a new Mac app or scaffold a macOS project.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# New Mac app
The template builds and runs as is. The first build proves the toolchain
works before you write feature code.
## What the template is
A Swift package with one executable target, plus a script that wraps the
binary in a real `.app` bundle. An agent can read and edit every file.
```text
<AppName>/
Package.swift macOS 26, Swift 6.2 tools, main-actor default isolation
Info.plist.in bundle id, name, icon, minimum macOS
Icon/AppIcon.icon the app icon: Icon Composer file, JSON plus SVG layers
build.sh swift build -> .app bundle -> codesign -> ~/Applications
CLAUDE.md build, check, and design rules for agents
Sources/<AppName>/
App.swift window, menus, Settings, database location
Models.swift SwiftData models, sidebar pages, AppModel
ContentView.swift NavigationSplitView: sidebar, list, detail
Snapshot.swift APP_SNAPSHOT mode: PNG and layout file per page and Settings tab, light and dark
UI/Theme.swift accent colors, saved choice, accent tokens
SettingsView.swift Settings window: one tab per topic, sized to content
…Read the whole file at its exact version.
How to install
mdr add tomcounsell/ai/new-mac-app@sha256:f2c76bf9f4843d61The line at the top of this page pins the label git:20261027.b1054fc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
