Download Peeler

Or go to the Releases page and grab the .dmg file from the latest release — that's the only file you need. You can safely ignore the other files.

Since Peeler is not notarized, macOS may block it on first launch. To fix this, run:

xattr -rd com.apple.quarantine /Applications/Peeler.app

Then open the app normally.

Right-click the menu bar icon for History, Palettes, Settings, and Quit.

Requires Xcode 15+ and Swift 6.0.

# Run in debug mode
swift run

# Build the .app bundle
bash scripts/build-app.sh

# Package into a DMG
bash scripts/create-dmg.sh

# Package a Sparkle update ZIP
bash scripts/create-update-archive.sh

# Generate appcast.xml for published updates
bash scripts/generate-appcast.sh

Build output goes to build/Peeler.app, build/Peeler-1.0.0.dmg, and build/updates/.

Peeler now uses Sparkle for in-app updates.

1. Generate an EdDSA key pair with Sparkle's generate_keys tool.
2. Replace SUPublicEDKey in Sources/Peeler/Resources/Info.plist with your public key.
3. Build the app bundle with bash scripts/build-app.sh.
4. Create the update ZIP with bash scripts/create-update-archive.sh.
5. Run bash scripts/generate-appcast.sh to generate appcast.xml.
6. Upload the ZIP and appcast.xml to the host used by SUFeedURL.

By default SUFeedURL points to:

https://github.com/GithubAnant/peeler/releases/latest/download/appcast.xml

If you host updates elsewhere, change SUFeedURL in Sources/Peeler/Resources/Info.plist.
