After generating a unity build which works fine in the editor, I get this error in the title when I try to archive the build for App Store. My application uses both Firebase and Google AdMob, which from my research from online forums these two packages causes the problem most likely. Unfortunately I've not found any solution from the Google side. Additionally I get an error message in unity after the build but the build is created no matter what. I am not sure if this error happening because of a broken CocoaPods installation or some missing files/libraries in the build file. Any help would be appreciated. Thanks! Unity Error : iOS framework addition failed due to a CocoaPods installation failure. This will will likely result in an non-functional Xcode project. After the failure, "pod repo update" was executed and succeeded. "pod install" was then attempted again, and still failed. This may be due to a broken CocoaPods installation.
