我已尝试过您的代码，以下解决方案正在运行。

func downloadJsonWithURL() {
    let url = NSURL(string: self.url)
    URLSession.shared.dataTask(with: (url as URL?)!, completionHandler: {(data, response, error) -> Void in
        if let jsonObj = try? JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? NSDictionary {
            self.detailsArray = (jsonObj!.value(forKey: "data") as? [[String: AnyObject]])!
            print(self.detailsArray)
            for item in self.detailsArray{
                if let detailDict = item as? [String:AnyObject] {
                    if let name = detailDict["name"]{
                        self.titleName.append(name as! String)
                        print(self.productName)
                    }
                    self.childrenArray = (detailDict["children"]as? [[String : AnyObject]])!
                    print(self.childrenArray)
                }
            }
            OperationQueue.main.addOperation({
                print(self.productName)
                print(self.titleName)
                print(self.name)
            })
        }
    }).resume()
}

试试这个：

self.detailsArray = (jsonObj.value(forKey: "data") as? [[String: AnyObject]])!
      print(self.detailsArray)
      for item in self.detailsArray{
        if let detailDict = item as? [String : AnyObject] {
          if let name = detailDict["name"]{
            self.titleName.append(name as! String)
            print(self.productName)
          }
          if let dictChildren = detailDict["children"]{
        if ((dictChildren as? [Any]) != nil){
          self.childrenArray = dictChildren as! [[String : AnyObject]];
        }
        print(self.childrenArray)

      }
  }
