Ioso

Ioso, also known as iOS on Rails, is an open-source framework that facilitates the development of iPhone and iPad applications using the Ruby programming language and the Ruby on Rails web framework. It aims to leverage the familiarity and productivity of Ruby on Rails for native mobile development, allowing developers to share code and logic between their web applications and their iOS applications.

The core idea behind Ioso is to enable developers to write their application's business logic and potentially some of its user interface components in Ruby. This Ruby code can then be compiled or executed on iOS devices, typically through an intermediate layer or a Ruby interpreter designed for the platform. This approach can streamline the development process, especially for teams already proficient in Ruby on Rails, by reducing the need to learn and manage separate codebases for web and mobile.

Ioso provides tools and libraries that bridge the gap between the Ruby environment and the native iOS SDK. This includes ways to interact with iOS APIs, build user interfaces, and manage application data. The framework typically handles the complexities of interoperability, allowing developers to focus on the application's features rather than low-level platform details. While not as widely adopted as native iOS development with Swift or Objective-C, Ioso represents an interesting approach for developers seeking to utilize their existing Ruby expertise in the mobile space.
