Hi! I started a swift IOS app and I follow the steps adapting the code to swift programing (the sample is in objetive-c). Now, “ViewController.swift” file only don’t recognize the followings variables:

- WOWZStateIdle, WOWZStateStarting, WOWZStateRunning, WOWZStateStopping, WOWZFrameSizePreset1280x720

I thought that could be the SDK import (Import WowzaGoCoderSDK), but others words are perfect recognize for Xcode. So, I think that the problem is that XCode don’t load WOWZStatus.h

thanks a lot!
