Answer 1

I've called insertionPointColor in viewDidLoad and app crashes.

I fixed this by calling insertionPointColor on viewDidAppear.

For Swift developers:

Set insertionPointColor method into extension:

extension NSTextField {
    public func customizeCursorColor(_ cursorColor: NSColor) {
        let fieldEditor = self.window?.fieldEditor(true, for: self) as! NSTextView
        fieldEditor.insertionPointColor = cursorColor
    }
}

and call

 override func viewDidAppear() {
        super.viewDidAppear()
        textField.customizeCursorColor(NSColor.red)
    }
