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. See: https://guides.cocoapods.org/using/troubleshooting.html for potential solutions.

pod install output:

Analyzing dependencies
[!] Unable to find a specification for `mopub-ios-sdk/Core (= 5.12.1)`

You have either:
* out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
* mistyped the name or version.
* not added the source repo that hosts the Podspec to your Podfile.





pod repo update output:

Bu unity hatası gibi gözükmüyor, unityden ios çıktı aldıktan sonra terminalde aldığınız hatalar sanırım. Macosta cocoapods yüklü mü? Yüklü ise gerekli updateler yapıldı mı? Podları yüklemek için Terminalden hangi kodları yazıyorsunuz?
