Hyperledger Iroha iOS library

Please pay attention! Current version of the library was tested and compatible with Iroha 1.0.0-rc2.

The library was created to provide convienent interface for iOS applications to communicate with Iroha blockchain including sending transactions/query, streaming transaction statuses and block commits.


For new iroha users we recommend to checkout iOS example project. It tries to establish connection with Iroha peer which should be also run locally on your computer to create new account and send some asset quantity to it. To run the project, please, go through steps below:

  1. Follow instructions from Iroha documentation to setup and run iroha peer in Docker container.

  2. Clone current repository.

  3. cd Example directory and run pod install.

  4. Open IrohaCommunication.xcworkspace in XCode

  5. Build and Run IrohaExample target.

  6. Consider logs to see if the scenario completed successfully.

Feel free to experiment with example project and don’t hesistate to ask any questions.
