                print("JSON serialization failed")

        } else {

            print("ERROR FOUND HERE")

    task.resume()

你能帮忙吗

错误消息清楚地告诉您，反序列化对象是数组而不是字典

let jsonResult = try JSONSerialization.jsonObject(with: urlContent, options: []) as! [[String:Any]]
for item in jsonResult {
  print(item["malzemeler"] as! String) // cast directly to String
}

注:

Swift 3中未指定的JSON字典类型是
```
[String:Any]
```
```
mutableContainers
```
选项在Swift中无效
