Intercommunication between to macOS apps on local Mac
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
Is there an easy way, in Swift, for one macOS app to send a message to another macOS app on the same mac (localhost). I have two macOS apps, one of them is a menu app. There are some situations the standard macOS app need to send a notification (a one way ticket, fire and forget) to the menu app.

There are dozens of different options of how to achieve this. Each with their own advantages and disadvantages.
Probably the easiest is sending notifications using the DistributedNotificationCenter from Foundation. It’s just like the regular NotificationCenter but across Process-Boundaries.
On the receiving side you register an observer like this:
DistributedNotificationCenter.default().addObserver(forName: NSNotification.Name("com.mycompany.MyNotification"), object: nil, queue: nil) { notification in
print(notification)
}
On the sending side you post a notification like this:
DistributedNotificationCenter.default().post(name: NSNotification.Name("com.mycompany.MyNotification"), object: nil, userInfo: ["data": "to send"])
This is not very secure though - any process can send and receive those notifications. So if they contain private data you shouldn't use this method. This also means you should use a unique notification name. Good idea to start that with a reversed DNS name like com.mycompany. here.
If your app is sandboxed there is another limitation that you cannot send an userInfo dictionary.

Great, I will test it.. the message does not include private data, it is only a message to the menu app to reload data from persistent storage... Thank you for answering my question.. The app is not sandboxed (github.com/rsyncOSX/RsyncOSX)
