# Contacts
> Contacts — CometChat documentation.
`CometChatContacts` is a `UIViewController` specifically designed to facilitate the display and management of users and groups within chat applications. It streamlines the process of showcasing all app users and available chat groups in a user-friendly interface, making it easier for users to connect and communicate effectively. Additionally, the view controller includes a `UISegmentedControl` to switch between the users and groups list, enhancing navigation and usability.
Key Features:
1. **User List View**: CometChatContacts presents a comprehensive list of all registered users within the application. This list allows users to quickly find and select specific individuals they wish to interact with.
2. **Group List View**: The component also offers a dedicated view to showcase all the available chat groups. This simplifies the process of joining or creating new group conversations.
3. **Smart Search Functionality**: Users can utilize the powerful search feature to quickly locate specific users or groups by typing names or keywords. This ensures seamless navigation, even in applications with a large user base.
4. **Selection Mode**: CometChatContacts supports a selection mode, enabling users to pick multiple contacts or groups simultaneously. This feature proves useful for creating group chats or forwarding messages to multiple recipients.
5. **Customizable Tab Layout**: Developers can easily customize the appearance of the tabs, including text colors, indicator color, and background, to match the app's branding and aesthetics.
6. **Selection Limit Control**: Developers have the flexibility to set a selection limit, restricting the number of contacts or groups a user can select during the selection mode. This helps maintain messaging policies and optimize user experience.
7. **User-Friendly Close Button**: The component provides a convenient close button feature, allowing users to exit the Contacts view and return to their previous screen or chat interface effortlessly.
