CocoaPods could not find compatible versions for pod "Firebase/Core"

Here is my Podfile:

source 'https://github.com/CocoaPods/Specs'
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'

target 'Unity-iPhone' do
pod 'Google-Mobile-Ads-SDK', '7.3.1'
pod 'Firebase/Core'
end

It works well when I run 'pod install'

output:

Analyzing dependencies
Downloading dependencies
Using Firebase (4.13.0)
Using FirebaseAnalytics (4.2.0)
Using FirebaseCore (4.0.20)
Using FirebaseInstanceID (2.0.10)
Using Google-Mobile-Ads-SDK (7.3.1)
Using GoogleToolboxForMac (2.1.4)
Using nanopb (0.3.901)
Generating Pods project
Integrating client project
Sending stats
Pod installation complete! There are 2 dependencies from the Podfile and 7 total pods installed.

Perfect, everything is fine,But if I add a specific version with FirebaseCore,like below code:

pod 'Firebase/Core','4.0.20'

and 'pod install' again

output:

[!] CocoaPods could not find compatible versions for pod "Firebase/Core":
  In Podfile:
    Firebase/Core (= 4.0.20)

None of your spec sources contain a spec satisfying the dependency: `Firebase/Core (= 4.0.20)`.

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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.

Actually,FirebaseCore with 4.0.20 is exist,So how should I fix it?

Run the following commands in your project/ios folder in the order:

pod update Firebase/Core 
pod install --repo-update

The podspec versioning for Firebase and FirebaseCore are separate, so you shouldn't use them interchangeably. The Firebase pod is a parent for the subspecs Firebase/Core, Firebase/Analytics, etc., but FirebaseCore is not using the same versioning because FirebaseCore is not a subspec of Firebase, whereas Firebase/Core is.

For reference, the Firebase podspec is here: https://github.com/CocoaPods/Specs/blob/980d013a857e7ef973531f1cf85ddb5b8a56d1b0/Specs/0/3/5/Firebase/5.10.0/Firebase.podspec.json

I fixed it right now, just change Firebase/Core to FirebaseCore (I was checked FirebaseCore.podspec file in GitHub.)
