Snippet to programmatically set initial position of an Cocoa window

MyInitiallyPositionedWindowController.swift

import Cocoa

class MyInitiallyPositionedWindowController: NSWindowController {

    override func windowDidLoad() {
        super.windowDidLoad()
        
        if let window = window, screen = window.screen {
            let screenRect = screen.visibleFrame
            let offsetFromLeft = CGFloat(200)
            let offsetFromTop = CGFloat(200)
            let offsetFromBottom = screenRect.maxY - window.frame.height - offsetFromTop
            window.setFrameOrigin(NSPoint(x: offsetFromLeft, y: offsetFromBottom))
        }
    }
}
