Cannot add UnityAds delegate in latest SDK version

Hey,

Using the latest SDK version 3.6.0 and with CocoaPods trying to implement UnityAds with delegate in iOS Swift:

class CALSS: NSObject, UnityAdsDelegate {
       func configureUnityAds() {
           UnityAds.initialize("NUMBER", delegate: self)
       }
}

Gives an error: “Type of expression is ambiguous without more context”

Also when trying to use the addDelegate method getting the same results:

UnityAds.initialize("")
UnityAds.add(self)

Any suggestions?

Anyone?

Help someone?
