control center widgets

Control Center widgets, also known as controls, were introduced in iOS 18 and are a new type of widget that allows quick access to actions from your app. These controls can be added to various system spaces, including Control Center, the lock screen, and the action button. They are built using WidgetKit and can perform actions using app intents.

Here are some key points about Control Center widgets from the session "Extend your app’s controls across the system":

1. Types of Controls: There are two types of controls: buttons and toggles. Buttons perform discrete actions, while toggles change a piece of boolean state (e.g., turning something on or off) (Extend your app’s controls across the system).

2. Building a Control: Controls are built similarly to widgets and use the same underlying architecture. You can define a control by providing information such as a symbol, title, tint, color, and the action it performs (Extend your app’s controls across the system).

3. Configurable Controls: Controls can be made user-configurable, allowing users to customize their behavior. For example, a timer control can be configured to start and stop different timers based on user selection (Extend your app’s controls across the system).

4. Integration with System Spaces: Controls can be placed in Control Center, the lock screen, or the action button, and they sync across all devices. This allows for seamless interaction with your app's key actions from various parts of the system (Extend your app’s controls across the system).
