Description

This project is an example of set frameworks implementations that may help you to interact with the Ethereum blockchain.

Getting started

• Install Needle DI brew install needle source brew

Project structure

• Package Manager is also Apple native SPM
• Dependency Manager is Needle ~> 0.18.1, which made and used by Uber. It's better that Swinject because gives dependency missing errors on compile time and decreases our app speed by not overloading runtime.

Dependencies

• Secure Data Storage with KeychainSwift , but simplify usage with framework KeychainSwift ~> 20.0.0
