Firebase & CocoaPods Issue
The issue was reported and solved by one of our good customer, very grateful for sharing it with us. I hope this article would be helpful for somebody who will experience the same.
Error building Player: 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 [!] CocoaPods could not find compatible versions for pod "Firebase/Analytics": In Podfile: Firebase/Analytics (= 5.9.0) None of your spec sources contain a spec satisfying the dependency: `Firebase/Analytics (= 5.9.0)`.
<iosPod name="Firebase/Messaging" version = 5.9.0
<iosPod name="Firebase/Messaging" version = 5.1.0
