`Meta`

Meta is a framework allowing the creation of user interface (UI) frameworks in Swift.

Overview

Meta follows the following principles:

It is a declarative framework, meaning that instead of writing how to construct a user interface, you write what it looks like.
The user interface is treated as a function of its state. Instead of directly modifying the UI, modify its state to update views.
Multiple UI frameworks can be used in the same code, but the selection of the framework happens when executing the app. This enables the creation of cross-platform UI frameworks combining several UI frameworks rendering always with the same backend.

It knows the following layers of UI:

An app is the entry point of the executable, containing the windows.
A scene element is a template for a container holding one or multiple views (e.g. a window).
A view is a part of the actual UI inside a window, another view, or another renderable component.
Custom renderable components can be used for more restrictive UI elements, such as menus.
