React Native Fetch Blob issue pod not installing for IOS

Using React Native Fetch Blob to perform some action. But the IOS platform not installing in pod file. Showing this...

[!] CocoaPods could not find compatible versions for pod "React/Core":
  In Podfile:
    react-native-fetch-blob (from `../node_modules/react-native-fetch-blob`) was resolved to 0.10.6, which depends on
      React/Core

None of your spec sources contain a spec satisfying the dependency: `React/Core`.

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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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

Kindly suggest some solution for that issue.
