The latest iOS SDK version is [5.8.1](https://github.com/line/line-sdk-ios-swift), and the latest Android SDK version is [5.7.0](https://github.com/line/line-sdk-android). Besides, the usage in react-native had some change. I open a pull request for the upgrade, and also work on our project. https://github.com/xmartlabs/react-native-line/pull/90 May the power be with the repo.
