The steps to build leaf.xcframework are the same as for iOS, and the built leaf.xcframework can be used for both iOS and macOS. Please refer to the method in the iOS demo readme.
Similarly, place the leaf.xcframework in the root directory of the current demo so that you can open the project file teonvpn-macos-demo.xcodeproj with Xcode and compile it.
The macOS demo is basically the same as the iOS demo.
This demo demonstrates the JSON format of leaf configuration, which is more flexible than the .conf format. The .conf format has a drawback that it does not escape #, causing parsing errors if a proxy configuration item contains #.
In the macOS demo, the environment variable LOG_CONSOLE_OUT=true is set in PacketTunnel/PacketTunnelProvider.swift to allow leaf's logs to be output to Console.app.
