React Native Fetch Blob issue pod not installing for IOS

Question

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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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