The Cocoapods installation offers up to 4.8.0, but in reality, we can only use up to version 4.0.0
The issue with cocoapod installation has been fixed. You can install 4.8.0 by adding line below to your Podfile and running
pod 'EkoChat', :source => "https://github.com/EkoCommunications/EkoMessagingSDK.git"
We tested this on our side and it seems to be working fine. This issue can arise if the cocoapod specs repo on the machine where pod is being installed is outdated.
pod repo update followed by
pod install --repo-update
