I'm trying to make a status bar app that reminds me when my mac has reached a charge of 100%. I need to keep updating the charging variable so that I can know when to send the notification. All the while loops fail to display my icon on the status bar, and whenever I hover over the empty space it creates, the rainbow spinning wheel is displayed.

I tried to use didset but it doesn't show a notification at all.

Note: The problem is not with the notification or the getbatterystate, I've used a simple print in place of the notification function and nothing displayed either. For the getbatterystate I've printed it, and an integer did show up

    var charge: Int = Int(getBatteryState())!{
        didSet{
            if charge == 40{
                showNotification()
            }else{
                showNotification()
                charge = Int(getBatteryState())!
            }
        }
    }

An infinite (while) loop is a bad idea. Just use a `Timer` which fires once per second (or even once per 10 seconds is sufficient). In the action (or block) get the battery state and send the notification if necessary. – vadian Aug 14 '18 at 08:49
