• Build your own custom macOS apps with different webviews
• Switch between the tabs with ⌘ shortcuts
• Bridge web notifications to macOS Notification Center

Quick Start

./create-mac-app <YOUR_APP_NAME> <YOUR_ICON_PNG_PATH>
open <YOUR_APP_NAME>.app/Contents/Resources/config.json # edit your app's websites
open <YOUR_APP_NAME>.app # open and use your custom app

These instructions were developed and tested with Swift 4.2 on macOS 10.13 High Sierra.

Common Issues

1. If you have XCode installed and see one of these errors when running create-mac-app:

   • error: terminated(72): xcrun --sdk macosx --find xctest output:
         xcrun: error: unable to find utility "xctest", not a developer tool or in PATH
     

   • dyld: Library not loaded: @rpath/llbuild.framework/Versions/A/llbuild
     Referenced from: /Library/Developer/CommandLineTools/usr/bin/swift-package 
         Reason: image not found
         Abort trap: 6
     

   Try this fix, which tells XCode Command Line Tools where to find the most up-to-date libraries:

   sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
   

2. If you use macOS 10.12 or earlier and see the following error when running create-mac-app:

   Package.swift:12:5: error: argument 'targets' must precede argument 'dependencies'
       targets: [
       ^
   Can't parse Package.swift manifest file because it contains invalid format. Fix Package.swift file format and try again.
   

   You are probably using Swift 3. You can confirm that by running swift --version. Switching to the swift3 branch should probably get you up and running.

   git checkout swift3
