[Bug] Cannot build via Unity Cloud Build for iOS after installing Remote Config SDK

[PhilBerDood]

Description

When installing Analytics and Crashlytics, it builds fine. However, as soon as I just install Remote Config, Unity Cloud Build fails when trying to build an iOS build. The following error appears:

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

pod install output:

CocoaPods 1.16.1 is available.
To update use: gem install cocoapods

For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.16.1

[!] CocoaPods could not find compatible versions for pod "Firebase/RemoteConfig":
In Podfile:
Firebase/RemoteConfig (= 11.9.0)

Specs satisfying the Firebase/RemoteConfig (= 11.9.0) dependency were found, but they required a higher minimum deployment target.

There doesn't seem to be any difference in minimum deployment target between the three install SDK's so I'm just not sure why it's not working for RemoteConfig.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hey @PhilBerDood, thanks for reaching out.

Currently I'm testing the Firebase Remote Config version 12.7.0 on iOS simulator 18.2 and seems to work normally. I'm unable to check if iOS 13 simulator would encounter a build/runtime issue since this requires a version lower than Sequoia 15.3.1 macOS.

That said, could you answer a few questions below, so we can investigate this further:

1. Could you share with us what iOS version did you set for the minimum deployment target?
2. Could share the content of your Podfile? (Please remove any (PII) Personally identifiable information.)
3. You mentioned that the Unity Cloud Build fails for this build. Does building on the local machine also causes this issue?
4. Any chance you can share an MCVE?
