How to solve Firebase Crashlytics update issue in swift 4.0 project in iOS?

I'm working Swift 4 and minimum deployment target set to 10.0, I already installed crashlytics sdk manually. The crashlytics version I am using is below 4.0.0, now I want to update to 4.0.0 above version. I tried pod 'Firebase/Crashlytics' in terminal and I got this error:

Analyzing dependencies [!] CocoaPods could not find compatible versions for pod "Firebase/Crashlytics":

I can't mention any number of version but I faced this issue. Can you please help me resolve this issue?

Firebase console error

Terminal console error

Thank you
