var jsonData:NSData?
do{
jsonData = try NSData(contentsOfURL: NSURL(string: url)!, options: NSDataReadingOptions.DataReadingUncached)
let jsonObject:AnyObject? = try NSJSONSerialization.JSONObjectWithData(jsonData!, options: NSJSONReadingOptions.AllowFragments)
if let itemArray = jsonObject?.objectForKey("items") as? NSArray{
for item in itemArray{
if let sysItem = item.objectForKey("sys"){
//this is createdAt
if let createdAt = sysItem.objectForKey("createdAt") as? String{
print("createdAt:\(createdAt)")
}
if let contentTypeItem = sysItem.objectForKey("contentType")!.objectForKey("sys"){
//this is id
if let id = contentTypeItem.objectForKey("id") as? String{
print("id:\(id)")
}
}
}
}
}
}catch let err as NSError{
print("err:\(err)")
}
This code dosen't use any libraries,but you can use SwiftyJSON,this is will be easy to parse json.
Hope this help.

Thanks! Solved my problem :).
This can be done in simple way. I am assuming that you have parsed your json to dictionary
You have a key with items which is an array of dictionary and inside that dictionary you have createdAt and id(well it is deeper into the hierarchy but I will show you how to get it) keys. You can access it by simply doing this.
for dict in jsonDict["items"] as! Array<NSDictionary> {
let sysDict = dict["sys"] as! NSDictionary
print(sysDict["createdAt"]) //prints all createdAt in the array
let contentDict = sysDict["contentType"]
print((contentDict["sys"] as! NSDictionary)["id"]) // prints all ids
}
Hope this helps.
