JSON Structure pour analyser les données JSON

Question

Je veux analyser ce JSON, au plus haut niveau JSON entrant est un tableau, comment accéder aux informations du dictionnaire dans le tableau?

[ 
     { 
     "id": 1, 
     "name": "Leanne Graham", 
     "username": "Bret", 
     "email": "Sincere@april.biz", 
     "address": { 
      "street": "Kulas Light", 
      "suite": "Apt. 556", 
      "city": "Gwenborough", 
      "zipcode": "92998-3874", 
      "geo": { 
      "lat": "-37.3159", 
      "lng": "81.1496" 
      } 
     }, 
     "phone": "1-770-736-8031 x56442", 
     "website": "hildegard.org", 
     "company": { 
      "name": "Romaguera-Crona", 
      "catchPhrase": "Multi-layered client-server neural-net", 
      "bs": "harness real-time e-markets" 
     } 
     } 
] 

c'est mon code mais je ne sais pas comment détecter les données du dictionnaire.

func profileFromJSONData(data : NSData) -> ProfileResult { 

     do{ 
      let jsonObject : [[String:AnyObject]] 
      = try NSJSONSerialization.JSONObjectWithData(data, options: []) as! [[String:AnyObject]] 

      for profileJSON in jsonObject { 
       if let profile = profileFromJsonObject(profileJSON) { 
        finalProfile.append(profile) 
       } 
      } 
      return .Success(finalProfile) 
     } 
     catch let error { 
      return .Failure(error) 
     } 

    } 

est ma méthode de profileFromJsonObject pour JSON analyse syntaxique en instance de profil

func profileFromJsonObject(json: [String:AnyObject]) -> UserProfile?{ 

     guard let 
      id = json["id"] as? Int, 
      name = json["name"] as? String, 
      userName = json["username"] as? String, 
      email = json["email"] as? String, 
      address = json["address"] as? NSDictionary, 
      phone = json["phone"] as? String, 
      website = json["website"] as? String, 
      company = json["company"] as? NSDictionary 
      else { 
       return nil 
     } 

    let obj = UserProfile(id: id, name: name, userName: userName, email: email, address: address, phone: phone, website: website, company: company) 
     return obj 
    }

J'ai essayé votre JSON en le prenant dans le fichier local, et je suis capable d'analyser à l'objet modèle de la manière suivante. Vous venez de mettre votre JSON à distance dans mon code, je l'espère travailler

func getTheLocalJSON() 
{ 
    let filePath = NSBundle.mainBundle().pathForResource("test", ofType: "json"); 
    let data = NSData.init(contentsOfFile: filePath!); 

    var json : NSArray! 
    do{ 
     json = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.AllowFragments) as! NSArray; 
    }catch{ 

    } 

    print("json \(json)"); 

    let dictResponse = json.objectAtIndex(0) as! NSDictionary; 

    let objUser = profileFromJsonObject(dictResponse)! as UserProfile; 

    print("user : \(objUser)"); 

    //Code to access company name and show it as screen title 
    self.title = (objUser.company)!["name"] as? String; 

    lblCompanyname.text = (objUser.company)!["name"] as? String; 
    lblCatchPhrase.text = (objUser.company)!["catchPhrase"] as? String; 
    lblbs.text = (objUser.company)!["bs"] as? String; 

} 

func profileFromJsonObject(json: NSDictionary) -> UserProfile?{ 

    guard let 
     id = json["id"] as? Int, 
     name = json["name"] as? String, 
     userName = json["username"] as? String, 
     email = json["email"] as? String, 
     address = json["address"] as? NSDictionary, 
     phone = json["phone"] as? String, 
     website = json["website"] as? String, 
     company = json["company"] as? NSDictionary 
     else { 
      return nil 
    } 

    let obj = UserProfile(id: id, name: name, userName: userName, email: email, address: address, phone: phone, website: website, company: company) 

    return obj 
}
