The UIExplorer test app shows the issue:

As you can see, they're all the same color when they should not be. 😉

Yes, NSImage has no tintColor as UIImage on iOS does. So currently it's like a placeholder. Although, I can implement it by applying image transformations.

Yeah, my current experimentation with that has got me to here:

extension NSImage {
    func tint(color: NSColor) {
        lockFocus()
        color.set()
        NSRectFillUsingOperation(NSMakeRect(0, 0, self.size.width, self.size.height), .sourceAtop)
        unlockFocus()
        isTemplate = false
    }
}
