斯威夫特。如何允许将URL从浏览器拖动到NSView

class MyView: NSView {
    override func draggingEntered(_ sender: NSDraggingInfo) -> NSDragOperation {
        if sender.draggingPasteboard.contains(types: [NSPasteboard.PasteboardType.URL]) {
            return .copy
        }
        return []
    }
    
    override func performDragOperation(_ sender: NSDraggingInfo) -> Bool {
        guard let pasteboard = sender.draggingPasteboard.propertyList(forType: NSPasteboard.PasteboardType(rawValue: "NSFilenamesPboardType")) as? NSArray,
              let fileURLs = pasteboard as? [URL] else {
            return false
        }
        
        for fileURL in fileURLs {
            // 处理拖放的URL
            print(fileURL)
        }
        
        return true
    }
}

let myView = MyView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))
self.view.addSubview(myView)
