Answer 1

If you want to create a separate class for New Window, these are the steps:

1. Create a class which is a sub class of NSWindowController e.g. NewWindowController
2. Create a window xib for NewWindowController class.

3. On button click code as:

   NewWindowController *windowController = [[NewWindowController alloc] initWithWindowNibName:@"You Window XIB Name"];
   [windowController showWindow:self];
   

Answer 2

NSWindowController * wc=[[NSWindowController alloc] initWithWindowNibName:@"your_nib_name"];
[wc showWindow:self];

Answer 3

Swift 3: In your storyboard go to WindowController -> Identity inspector -> storyBoardID: fill out: mainWindow. Then from your current viewcontroller link the button on the storyboard to the following method:

@IBAction func newWindow(_ sender: Any) {
    let myWindowController = self.storyboard!.instantiateController(withIdentifier: "mainWindow") as! NSWindowController
    myWindowController.showWindow(self)
}
