# ``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 a menu.
|
|
- A menu is a list of buttons, other menus, and views. Certain views (such as menu buttons) allow menus to be used.
