+1 – I am also having this issue XCode 9 Beta 5, unity 5.6.2. Cannot seem to find an answer anywhere.

Same happened to me. I set the checked the “Symlink Unity libraries” in the Build settings and the problem went away.

The interesting thing is, that

  1. I had an earlier build (which might have been built with the “Symlink Unity libraries” checked)
  2. when I APPENDED to that build (without checked box) the error did not came up.

I also read somewhere, that builds submitted to the App Store shall not use this box checked, but I don’t get really why. (I think it’s been working for me for a while, but maybe I don’t remember properly.)

I had this issue after updated GoogleMobileAds SDK.

And then I solve it by changing the file: GoogleMobileAdsDependencies.xml

from
<iosPod name="Google-Mobile-Ads-SDK" version="~> 7.41">

to
<iosPod name="Google-Mobile-Ads-SDK" version="7.49.0">

Maybe you can try to lock the Vuforia pod version.
