swiftyJSON move into array - json

Question

I try to get start with swiftyJSON and parsing information in Swift so i start with this API to understand it:
http://api.androidhive.info/contacts/
So here is my Code
import Fuzi
import UIKit
import Alamofire
import SwiftyJSON
class ViewController: UIViewController {
var arrRes = [[String:AnyObject]]() //Array of dictionary
var JSON_TestURL = "http://api.androidhive.info/contacts/"
override func viewDidLoad() {
super.viewDidLoad()
//get JSON
Alamofire.request(.GET, JSON_TestURL).responseJSON { (responseData) -> Void in
let swiftyJsonVar = JSON(responseData.result.value!)
//print(swiftyJsonVar)
//get JSONarray Name and write it into new Array
if let resData = swiftyJsonVar["contacts"].arrayObject {
self.arrRes = resData as! [[String:AnyObject]]
}
//count array and give "tag"
print(self.arrRes.count)
for var index = 0; index < self.arrRes.count; ++index {
var dict = self.arrRes[index]
let x = dict["name"] as? String
print(x)
print("")
}
}
}
getting the name, id etc is no problem but when i try to get the phone number i can't find a way.

Answer 1

for var index = 0; index < self.arrRes.count; ++index {
var dict = self.arrRes[index]
let x = dict["phone"]!["mobile"] as? String
print(x)
//print("")
}

When using SwiftyJSON you don't have to cast the objects like you do with NSJSONSerialization. You don't have to use this way of looping either when a simple call to map will do the trick.
For example, replace all this:
if let resData = swiftyJsonVar["contacts"].arrayObject {
self.arrRes = resData as! [[String:AnyObject]]
}
print(self.arrRes.count)
for var index = 0; index < self.arrRes.count; ++index {
var dict = self.arrRes[index]
let x = dict["phone"]!["mobile"] as? String
print(x)
}
with this:
let contacts = swiftyJsonVar["contacts"].arrayValue
let allMobilePhones = contacts.map { $0["phone"]["mobile"].stringValue }
print(allMobilePhones)
