Google mobile ads in unity (iOS) shows error

Question

I'm using google mobile ads in unity (iOS). I take the build in Xcode during linking.

It shows the following errors:

The main problem it's that unity It's not able to run/find the Cocoa pods main files and install the Pods automatically. That is what I did to fix the problem:

Be sure that on unity you don't have any message about the impossibility to build pods file because pods it's missing inside Unity. If that's the case, you need to update/install cocoa pods into your mac. Here some tips about how to do that on OS El Capitan. But generally by run this command you should be fine:

sudo gem install -n /usr/local/bin cocoapods

Then close and reopen unity.

Open you Xcode folder, you should have a file that it's something like: "youProjectName.xcworkspace". If you have it, open it, if not that means that something when wrong when Unity try to run the PodFile inside you project. Try to run the PodInstall manually, you can do it by open the command line, go to your project folder and rune the command: pod install. Be sure that the Pods will be installed correctly and without any errors. Now you should see the "youProjectName.xcworkspace"un your main directory.
Id Steps 2 doesn't work try to deletes all the Pods files and directory and then add and install you own Pods as indicated here.
If that still doesn't work you only solution it's use an old versione of the Unity adMob sdks that you can download here. And this tutorial to manually install the the google ad mob sdk without using the PodsFile.
