[REQUIRED] Please fill in the following fields:

• Unity editor version: 2022.3.19f1
• Firebase Unity SDK version: 10.6.0
• Source you installed the SDK: UPM
• Problematic Firebase Component: Core
• Other Firebase Components in use: All
• Additional SDKs you are using: None
• Platform you are using the Unity editor on: MacOS
• Platform you are targeting: iOS
• Scripting Runtime:IL2CPP
• Pre-built SDK from the open-source from this repo: https://github.com/GameWorkstore, but I also double checked and downloaded prebuilt from website, and the result is the same.

[REQUIRED] Please describe the issue here:

Simply building from Unity targeting iOS build target in Unity Editor:

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
Adding spec repo `trunk` with CDN `https://cdn.cocoapods.org/`
[!] CocoaPods could not find compatible versions for pod "Firebase/Analytics":
  In Podfile:
    Firebase/Analytics (= 10.15.0)

None of your spec sources contain a spec satisfying the dependency: `Firebase/Analytics (= 10.15.0)`.

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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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:

Updating spec repo `trunk`

Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)? Yes
What's the issue repro rate? 100%

What happened? How can we make the problem occur?

On iOS build export.

Recommended Fix

Change how podfile is generated by removing the extra / in the name of the pod names for the FIrebase deps

[StephenHodgson]

Come to fine out, it is not actually the versions defined. It is the named entry into the Podfile file itself:

The pod names are incorrectly defined and have an extra / in the names.

for example Firebase/Analytics should be FIrebaseAnalytics etc.

currently broken:

source 'https://cdn.cocoapods.org/'

platform :ios, '12.0'

target 'UnityFramework' do
  pod 'Firebase/Analytics', '10.15.0'
  pod 'Firebase/AppCheck', '10.11.0'
  pod 'Firebase/Auth', '10.15.0'
  pod 'Firebase/Core', '10.15.0'
  pod 'Firebase/Crashlytics', '10.15.0'
  pod 'Firebase/Firestore', '10.15.0'
  pod 'Firebase/Functions', '10.15.0'
  pod 'Firebase/Messaging', '10.15.0'
  pod 'Firebase/RemoteConfig', '10.15.0'
  pod 'Firebase/Storage', '10.15.0'
  pod 'FirebaseInstallations'
end
target 'Unity-iPhone' do
end
use_frameworks! :linkage => :static

recommended fix:

source 'https://cdn.cocoapods.org/'

platform :ios, '12.0'

target 'UnityFramework' do
  pod 'FirebaseAnalytics', '10.15.0'
  pod 'FirebaseAppCheck', '10.11.0'
  pod 'FirebaseAuth', '10.15.0'
  pod 'FirebaseCore', '10.15.0'
  pod 'FirebaseCrashlytics', '10.15.0'
  pod 'FirebaseFirestore', '10.15.0'
  pod 'FirebaseFunctions', '10.15.0'
  pod 'FirebaseMessaging', '10.15.0'
  pod 'FirebaseRemoteConfig', '10.15.0'
  pod 'FirebaseStorage', '10.15.0'
  pod 'FirebaseInstallations'
end
target 'Unity-iPhone' do
end
use_frameworks! :linkage => :static

I noticed that FirebaseInstallations did not have a version, and was missing the / in the name. Prob a bug there as well in the version cmake script.

[StephenHodgson]

playing around I also was able to fix this with the / in the name by fixing the Firebase/AppCheck pod version to be the same as the rest: 10.15.0

[StephenHodgson]

come to find out not all of my packages were the same version.

Prob need to fix that FirebaseInstallations pod not being named correctly and missing its version tho
