Jkop is an API framework that aims to provide consistent or identical APIs and development experiences across different programming languages and technology platforms. It is also intended to act as a common layer between them. The Jkop project is composed of several modules, each of which is targeted for a specific purpose or environment.

The Jkop framework includes a number of widgets, which are reusable user interface components that can be used to construct good-looking, modern user interfaces for mobile devices as well as web and desktop applications. The Jkop Widget API offers a common development framework regardless of the underlying platform, but would use the underlying platform-specific mechanisms to provide the actual functionality.

In this tutorial, we will be making a simple iOS application using a text editor and the command line.
