Can someone please help me get rid of this? It was caused by something I got from the asset store but I ended up not using it and deleted it but the error is still there. Thanks Assembly 'Packages/com.unity.ads/Editor/UnityEditor.Advertisements.dll' will not be loaded due to errors: Unable to resolve reference 'UnityEditor.iOS.Extensions.Xcode'. Is the assembly missing or incompatible with the current platform? Reference validation can be disabled in the Plugin Inspector.
