Clear NSView programmatically in swift

I have a NSView connected to a custom class.
There’s some drawing on that view:

class LineDrawer: NSView {
    var linear = NSBezierPath()
    var storage = NSUserDefaults.standardUserDefaults()

    override func drawRect(dirtyRect: NSRect) {
        var color = NSColor()

        if let newLoadedData = storage.objectForKey("color") as? NSData {
            if let currentColor = NSUnarchiver.unarchiveObjectWithData(newLoadedData) as? NSColor {
                color = currentColor
            }
        }

        color.set()
        linear.lineWidth = CGFloat(storage.integerForKey("width"))
        linear.stroke()
    }

    override func mouseDown(theEvent: NSEvent) {
        super.mouseDown(theEvent)
        let location = theEvent.locationInWindow
        var lastPt = theEvent.locationInWindow
        lastPt.y -= frame.origin.y
        linear.moveToPoint(lastPt)
    }

    override func mouseDragged(theEvent: NSEvent) {
        super.mouseDragged(theEvent)
        var newPt = theEvent.locationInWindow
        newPt.y -= frame.origin.y
        linear.lineToPoint(newPt)
        needsDisplay = true
    }
}

And now I need to write a function to completely clear that view.

    Not too sure what you mean by completely clear that view but can’t you just fill it with a solid colour?

    [[NSColor windowBackgroundColor] setFill];
    NSRectFill(self.bounds);
    

    (Not up to speed with the Swift hotness yet)

    update
    I improving my Swift chops behold!

    NSColor.windowBackgroundColor().setFill()
    NSRectFill(self.bounds)
    

    Something like this should suffice. I used something like this in my project to clear NSView.

    while curView.subviews.count > 0 {
       curView.subviews.last?.removeFromSuperview()
    }
