Parse Json using SwiftyJson - ios

Question

I am able to get the entire JSon array parsed. It outputs to console with no issue. I can't seem to get the individual params from the array... my json looks like:
[{
City = NYC;
Device = "<null>";
DisplayAs = "Steve Hutson";
FirstName = Steve;
LastName = Hutson;
MobilePhone = "000-000-0000";
Org = "<null>";
Region = "";
Role = INSPECTOR;
SupervisorID = "73990";
email = "email#email.com";
fLast = shutson;
"gz_modtimestamp" = "2015-07-28 14:42:41";
id = 96;
isActive = YES;
lastupdated = "<null>";
sendemail = 1;
token = "<null>";
userpassword = "xxx";
},{
City = DET;
Device = "<null>";
DisplayAs = "Filipe Washington";
FirstName = Filipe;
LastName = Washington;
MobilePhone = "000-000-0000";
Org = "<null>";
Region = "";
Role = INSPECTOR;
SupervisorID = "6567";
email = "email#email.com";
fLast = shutson;
"gz_modtimestamp" = "2015-07-28 13:02:09";
id = 93;
isActive = YES;
lastupdated = "<null>";
sendemail = 1;
token = "<null>";
userpassword = "xxx";
}]
In my main ViewController.swift file my json request looks like:
var myData:NSData = getJSON("http://xxxx/getusersData.php")
var myDict:NSArray = parseJSON(myData)
println(myDict)
This prints my entire json object which is perfect. However my issue is, how do I get only the FirstName's in an array? By index this works:
println(myDict[0]["FirstName"]) how ever, it only brings back one item.
I am trying to insert specific json items into sqlite which i am using SQLite.swift but i need to know how to retrieve specific item parameters as I would if i was using AJAX.
I am trying to retrieve FirstName, Email and UserPassword info.
Any help would be appreciated.

You can iterate over the JSON object and retrieve that info:
for (index: String, subJson: JSON) in json {
//Do something you want
var firstName = subJson["FirstName"].stringValue
var email = subJson["email"].stringValue
var userPassword = subJson["userpassword"].stringValue
// Build the sqlite query with the variables here
}
As a clarification, you don't access the values directly as in json["FirstName"], you must also use the type functions from SwiftyJSON. In your case they're both strings, so stringValue is used. If you needed and int, it'd be intValue.
There's also the option of just json["FirstName"].string in case the field is optional. Take a look at the readme
