The date of earliest is in a dictionary timeAdjustments in a dictionary searchCriteria

let object = JSON(readableJSON)
let earliest = object["searchCriteria"]["timeAdjustments"]["earliest"]["date"].stringValue
print(earliest)

Thanks, changed date to time now it says the same for each whereas should be a different time, when I add it inside the for loop, it's the same?!

NSJSONSerialization.JSONObjectWithData(jsonData!, options: []) as! [String:AnyObject] let object = JSON(readableJSON) let searchCriteria = object["journeys"] let earliest = object["searchCriteria"]["timeAdjustments"]["earliest"]["time"].stringValue   for option in searchCriteria.arrayValue {   let arrivalDateTime = option["arrivalDateTime"].stringValue   arrivalArray.append(arrivalDateTime)   earliestArray.append(earliest) }

There is only one earliest key in the entire text and you get only a different arrivalDateTime in the repeat loop. Maybe you mean startDateTime
