SessionSettingsBuilder

The SessionSettingsBuilder is a powerful configuration tool that allows you to customize every aspect of your call session before participants join. From controlling the initial audio/video state to customizing the UI layout and hiding specific controls, this builder gives you complete control over the call experience.

Proper session configuration is crucial for creating a seamless user experience tailored to your application’s specific needs.

These are pre-session configurations that must be set before joining a call. Once configured, pass the SessionSettings object to the joinSession() method. Settings cannot be changed after the session has started, though many features can be controlled dynamically during the call using call actions.

Swift

let sessionSettings = CometChatCalls.sessionSettingsBuilder
    .setTitle("Team Meeting")
    .setDisplayName("John Doe")
    .setType(.video)
    .setLayout(.tile)
    .startAudioMuted(false)
    .startVideoPaused(false)
    .build()

Objective-C

SessionSettings *sessionSettings = [[[[[[[CometChatCalls sessionSettingsBuilder]
    setTitle:@"Team Meeting"]
    setDisplayName:@"John Doe"]
    setType:CallTypeVideo]
    setLayout:LayoutTypeTile]
    startAudioMuted:NO]
    startVideoPaused:NO]
    build];
