For non required fields, you can either omit from the JSON string or set it to a default value
        (e.g. String = "", Integer/Double = 0, Boolean = false, DateTime = 1900-01-01T00:00:00.000Z)
    
    
        
            
            This sample code is to generate a function leveraging existing core functions you've already built.
            
                
func getAPIKit() -> (url: String, dict: Dictionary<String, AnyObject>) {
    let url = "https://api.peoplevine.com/customer.asmx/completeExternalAuthentication"
    
    return (url, finalDict)
  }
                
            
         
        
            
            To get started we reccomend that you download the Alamofire project to simplify integration: https://github.com/Alamofire/Alamofire, in addition to SwiftyJSON: https://github.com/SwiftyJSON/SwiftyJSON
