Unity Ads error from Unity to Xcode build

Question

I recently built my project fine from Unity to Xcode and it ran perfectly well. Since then I have added the Unity ads to my project in Unity (and then realised I no longer need that as it comes inside of unity 5.3 with Services) so I removed the download. However when I built to Xcode I notice 2 Unity Ads in the frameworks that are linked when built. I get this error:

I tried to remove one of the linked library Unity Ads but still get the same error, any ideas?

Answer 1

I found a workaround.

Open the Xcode project select the UnityAdsUnityWrapper.mm in the UnityAds folder Then uncheck the Target membership Unity-Iphone

Seems to work now.
