parsing JSON with Swift - ios

Question

I'm coming from android programming to Swift iOS programming and have a hard time parsing a json
here's String I try to parse :
{"response":[{"uid":111,"first_name":"someName","last_name":"someLastName","photo_100":"http:someUrl/face.jpg"}]}
here how I try to parse this :
if let dict = Utils.convertStringToDictionary(response)! as? [String: AnyObject]{
// this part is yet doing ok
if let response = dict["response"] as? [String: AnyObject]{
NSLog("let response \(response)")
if let first_name = response["first_name"] as? String {
NSLog("first_name = \(first_name)")
}
}
else {
NSLog("not an []")
}
the Log message gives me "not an []" as it can't make a response object. As far as I understand, I'm doing right as [String: AnyObject] is what is in "response" body of my json
Just in case, here's my Utils.convertStringToDictionary method:
public static func convertStringToDictionary(text: String) -> [String:AnyObject]? {
if let data = text.dataUsingEncoding(NSUTF8StringEncoding) {
do {
let json = try NSJSONSerialization.JSONObjectWithData(data, options: .MutableContainers) as? [String:AnyObject]
return json
} catch {
NSLog("Something went wrong")
}
}
return nil
}

Array in swift denotes with []
Dictionary in swift denotes with [:]
your response parameter is array of dictionary ... so it denotes with [[:]]
so just parse it with [[String: AnyObject]]
if let response = dict["response"] as? [[String: AnyObject]]{
for user in response{
NSLog("let response \(user)")
if let first_name = user["first_name"] as? String {
NSLog("first_name = \(first_name)")
}
}
}

Problem here is response is an array
if let response = dict["response"] as? NSArray{
for value in response as? NSDictionary{
print(value["uid"]) /// prints 111
print(value["first_name"]) /// prints someName
}
}

Try this code
if let dict = Utils.convertStringToDictionary(response)! as? [String: AnyObject]{
// this part is yet doing ok
if let response = dict["response"] as? NSArray{
NSLog("let response \(response)")
for dict in response{
if let first_name = dict["first_name"] as? String {
NSLog("first_name = \(first_name)")
}
}
}
else{
NSLog("not an []")
}
}
