Mac OS X - Wallpaper Changer

Swift code to change the Wallpaper for all screens. Currently, it changes only the current spaces' wallpaper. I'm working on a version to change in all spaces.

Usage: WallpaperChanger "/Users/username/SomeFolder/SomePicture.jpg"

import AppKit

func setWallpaper(wallpaperPath: String){
    var error : NSError?
    let sharedWorkspace = NSWorkspace.sharedWorkspace()
    let screens = NSScreen.screens()!
    let wallpaperUrl : NSURL = NSURL.fileURLWithPath(wallpaperPath)!

    for screen in screens{
        sharedWorkspace.setDesktopImageURL(wallpaperUrl, forScreen: screen as! NSScreen, options: nil, error: &error)
    }
}

if Process.arguments.count == 2 {
    let wallpaperPath = Process.arguments[1]
    setWallpaper(wallpaperPath)
} else {
    print("Usage: \(Process.arguments[0]) WALLPAPER")
}
