Swift：无法将types'__NSCFArray'的值转换为'NSDictionary'

我有来自网站的JSON数据。 我做了主要的字典，我可以parsing除了一个子字典以外的每一个数据。 我得到错误“Swift：无法将types'__NSCFArray'的值转换为'NSDictionary'”

我的数据的这个例子。 我不能parsing“天气”，但我可以parsing所有其他字典，如"wind" 。

  ["name": Mountain View, "id": 5375480, "weather": ( { description = "sky is clear"; icon = 01n; id = 800; main = Clear; } ), "base": cmc stations, "wind": { deg = "129.502"; speed = "1.41"; 

代码片段

  let windDictionary = mainDictionary["wind"] as! [String : AnyObject let speed = windDictionary["speed"] as! Double print(speed) let weather = mainDictionary["weather"] as! [String : AnyObject] print(weather) 

Answer 1

代表你的评论…我会说windDictionary是字典…

 Dictionary denotes in JSON with {} and Array denotes with [] // In printed response you may have array with () 

所以，你的天气部分是字典数组…你必须像parsing它

  let weather = mainDictionary["weather"] as! [[String : AnyObject]] // although please not use force unwrap .. either use `if let` or `guard` statement
