Chat Screen

Overview

The LMChatFeedViewController is responsible for managing a feed of chat conversations, including both group chats and direct messages (DMs). It implements a segmented control to switch between these two types of conversations and uses a page view controller to manage the content.

Functionality

UI Components

• containerStackView: A vertical LMStackView that holds the main UI components.
• segmentControl: A UISegmentedControl for switching between Group and DM views.
• pageContainerView: An LMView that contains the page view controller.
• pageController: A UIPageViewController for managing the different feed pages.

Properties

• viewControllers: An array of UIViewController instances representing the different pages.
• currentPageIndex: An integer tracking the currently displayed page index.

Methods

• setupSegmentControl(): Configures the appearance and behavior of the segment control.
• setupPageController(): Configures the page view controller and adds it to the view hierarchy.
• addControllers(): Adds the necessary view controllers to the viewControllers array.
• segmentChanged(_:): Handles changes in the segment control selection.
