title: (XCODE) ERROR: ld: 5 duplicate symbols for architecture arm64
body: <p>I know this is a very common error, but I believe I have tried every single solution I have seen already posted. I use Unity for my app and do not know much about xcode syntax. I also believe it might be coming from UnityAds but I do not know how to address it. Thank you very much for any and all help.
