Fetching podspec for `RNI18n` from `node_modules/react-native-i18n`
[!] The `RNI18n` pod failed to validate due to 1 error.
[!] The validator for Swift projects uses Swift 3.0 by default, if you are using a different version of swift you can use a `.swift-version` file to set the version for your Pod. For example to use Swift 2.3, run: 
    `echo "2.3" > .swift-version`:
    - ERROR | attributes: Missing required attribute `homepage`.

Solved by adding

s.homepage = "https://github.com/AlexanderZaytsev/react-native-i18n"

to react-native-i18n/RNI18n.podspec
