I am receiving the errors “Unknown identifier ip address ”

I am trying to network on iOs following the tutorials but it doesn’t work. I have followed a tutorial for iOS Multiplayer “mpStarTrooper”. But I am receiving the errors “Unknown identifier IP address” and “Unknown identifier port” while trying to publish it for iOS. I also went through another one which states to export it as an iOS app. But in this case I got more than 200 errors. What can be done? Any help?
