用SwifyJSON解析JSON

Question

下面是我試圖解析的JSON的結構。我希望能夠循環訪問這些問題。

{ 
    "status" : 200, 
    "C&Q" : [ 
    { 
     "category" : "Applicant Details", 
     "questions" : [ 
     { 
      "compulsory" : true, 
      "options" : "Mr.; Mrs.; Miss", 
      "input" : "radio", 
      "question" : "Title" 
     }, 
     { 
      "compulsory" : true, 
      "options" : "N\/A", 
      "input" : "text", 
      "question" : "Surname" 
     } 
     ] 
    }, 
    { 
     "category" : "Identification Documents", 
     "questions" : [ 
     { 
      "compulsory" : true, 
      "options" : "Passport;Drivers License;Voter ID;NHIS", 
      "input" : "radio", 
      "question" : "ID TYPE" 
     }, 
     { 
      "compulsory" : true, 
      "options" : "N\/A", 
      "input" : "date", 
      "question" : "Date of Issue (YYYY-MM-DD)" 
     } 
     ] 
    } 

這是代碼，但我只能通過索引訪問。也許有人可以通過示例代碼來了解如何遍歷以便我可以訪問questions數組。

let swiftyJsonVar = JSON(response.result.value!) 

guard let questions = swiftyJsonVar["C&Q"].arrayValue[0]["questions"].arrayObject as? [[String:AnyObject]] else 
{ 
    print("parsing failed") 
    return 
} 

這是我如何使用/計劃使用數組，它適用於上述解析。

let questionsStructs = questions.map(Questions.init) 
self.formsData = questionsStructs 

任何幫助將不勝感激。

var questions:[Question] = [] 
for (key,subJson):(String, JSON) in json["C&Q"] { 
    for (key,j):(String, JSON) in subJson["questions"] { 
     let question = Question(......) 
     questions.append(question) 
    } 
}
