iOS UI Kit — Release Notes

Release history for the EnableX iOS UI Kit, including new features, improvements, and bug fixes per version.

v2.2.3 introduces an improved UI specifically for 1-to-1 audio-only calls. When a participant joins without video, the kit now renders a purpose-built calling screen showing the remote participant's name and avatar over a gradient background, with overlay buttons for microphone toggle and exit. This replaces the generic video grid with an experience designed for voice calls.

Audio View Mode — 1-to-1 Audio Calls

Enable the audio call UI with overlay mic-toggle and exit controls by setting isAudioViewMode to true on the EnxSetting shared instance before the session connects:

EnxSetting.shared.isAudioViewMode = true

Customise the calling screen appearance by assigning an EnxAudioViewConfig instance to audioViewConfig:

EnxSetting.shared.audioViewConfig = EnxAudioViewConfig(
    gradientLayer1: UIColor(red: 0.04, green: 0.22, blue: 0.20, alpha: 1),   // top gradient colour
    gradientLayer2: UIColor(red: 0.01, green: 0.08, blue: 0.07, alpha: 1),   // bottom gradient colour
    nameTextColor: .white,                                                     // remote participant name
    sortNameTextColor: .white,                                                 // initials text colour
    sortNameBGColor: UIColor(red: 0.07, green: 0.55, blue: 0.44, alpha: 1)   // initials avatar background
)

The framework is distributed as an .xcframework bundle with bundled dSYMs for crash symbolication.

• Framework migrated from .framework to .xcframework format for improved compatibility with Apple Silicon and simulator builds
• Added support for dSYMs file for crash symbolication in Xcode and third-party crash reporters

• Full support for Audio-Only calls — WebRTC audio transport without any video streams
• All video-related UI components (camera preview, video tiles, camera toggle) are automatically hidden when the session is in audio-only mode

• Updated iOS Video SDK to use Single Peer Connection architecture — improves scalability and reduces connection overhead in large rooms
• Chat, File Share, and Typing Indicator now operate through the WebRTC data channel instead of a separate socket transport
• Kit updated to the latest Swift version for forward compatibility
