I have a few questions regarding daemons. Indeed, even the macos developer center has limited information resources. I want to develop an application daemon that runs after system boot without login. a) a Daemon; Is it a simple console application combined with a plist? Because there are almost no tutorials on daemon development related to xcode. If there is a code sample reference, can you share it here? b) Can daemons be downloaded from the app store? Because there must be a software that I can offer to everyone through the app store. Is the installation automatic like other app store apps? If anyone has experience and can share it, I would be very grateful. c) I am working on an api related to mirroring the screen to android phone. Do you think a daemon has full access to wifi/ble and screen capture APIs? I would be very happy to hear your suggestions.
