how to move NSWindow to a particular screen?

In my app I need to be able to move my app's windows between the screens programmatically. I'm working on my MacBookPro and I'm connected to DELL monitor. So what I want to do is to have a method that would move my app's window from my laptop screen to the external DELL one.

Does anyone know how to achieve it?

Any help is highly appreciated!

Following Steve Waddicor's comment, I tried putting the following code in override func viewDidLoad(){} and I was able to display a window on the main screen, on my laptop.

By changing screens[0] to screens[1], your window should be on your external display. I hope this helps somebody.

 DispatchQueue.main.async {
           //set up the main display as the display where window shows up
           let screens = NSScreen.screens
           var pos = NSPoint()
           pos.x = screens[0].visibleFrame.midX
           pos.y = screens[0].visibleFrame.midY
           self.view.window?.setFrameOrigin(pos)
      }

[NSScreen screens] gives you an array of NSScreens. The screen at index 0 is the one that's got your menu on.

So pick the other screen from the array, find it's visibleFrame and change the frame of your window to go inside it.
