Resizing NSScrollView

How can I resize NSScrollView using Swift?

class MainViewController: NSViewController {

    @IBOutlet weak var scrollView: NSScrollView!

    override func viewDidLoad {
        scrollView.setFrameOrigin(NSPoint(x: 340, y: 537))
        scrollView.setFrameSize(CGSize(width: scrollView.contentSize.width, height: 102.0))
    }

}

The above code works only if there are no constraints set. But, without constraints, the ScrollView doesn't stay in place when the window is resized.

So this worked for me since my ScrollView was positioned on the top left:

scrollView.setFrameOrigin(NSPoint(x: self.view.frame.minX + 340, y: self.view.frame.maxY - 172))
scrollView.setFrameSize(CGSize(width: scrollView.contentSize.width, height: 102.0))

And the below image shows the settings used in Size Inspector to enable auto resize and also to stay to the top-left of the window.

If you are trying to set the document size (scrollable area) of a NSScrollView, then all we need to do is set the document view's size.

📌 Note: This assumes there are no constraints on the document view.

scrollView.documentView?.setFrameSize(NSSize(width: 576, height: 56))

If you are trying to scroll to a specific region, see scrollToVisible(_:).
