Getting this error when trying to implement Chartboost on Swift xcode? -


i have code add appid , app signature appdelegate.swift file error on last line of code. says: "cannot invoke startwithappid argument list of type (string, string, delegate: appdelegate). doing wrong? thanks!

  func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: [nsobject: anyobject]?) -> bool {     let kchartboostappid = "5236547547457856858568"     let kchartboostappsignature = "523525225"      chartboost.startwithappid(kchartboostappid, appsignature: kchartboostappsignature, delegate: self)     } 

i forgot add chartboostdelegate initializer. works now!
