The icon is not Yosemite themes (Light/Dark) compatible

[munas]

I just started to learn programming for Apple devices and believe that Swift is the correct choice.
I tried to modify your code and make the icon compatible with OS X Yosemite themes. However, have no luck.
If to use black icon, after Yosemite theme switched to the Dark mode the icon gets invisible.
Adding image.setTemplate(true) has no effect.
Do you have any solution that would make your code Yosemite themes compatible?

   init(imageName: String, item: NSStatusItem)
    {

        self.image = NSImage(named: imageName)!

        self.item = item
        self.isSelected = false

    image.setTemplate(true)

        self.onMouseDown = {}


        let thickness = NSStatusBar.systemStatusBar().thickness
        let rect = CGRectMake(0, 0, thickness, thickness)

        super.init(frame: rect)
    }

Well, I got kind of a workaround. Not as sophisticated as setTemplate, but it works. See: https://github.com/andinfinity/idrop.link-osx/blob/master/idrop.link/IconView.swift#L88
