Here is a Swift solution to this issue that I received from Apple Developer Technical Support:

override func canCloseDocumentWithDelegate(delegate: AnyObject, shouldCloseSelector: Selector, contextInfo: UnsafeMutablePointer) {
    super.canCloseDocumentWithDelegate(self, shouldCloseSelector: "document:shouldClose:contextInfo:", contextInfo: contextInfo)
}

func document(doc:NSDocument, shouldClose:Bool, contextInfo:UnsafeMutablePointer) {
    if shouldClose {
        // 
        doc.close()
    }
}
