Migration Guide from Frozen Mountain to Agora: iOS Edition

The text discusses how to integrate Agora's voice, video, and live-broadcasting software into an iOS app that previously used Frozen Mountain (Icelink) for similar functionality. It provides a step-by-step guide on how to replace the Icelink SDK with Agora's SDK using CocoaPods. The guide covers setting up the Agora singleton, initializing local and remote video views, joining a channel, handling incoming users, leaving the channel, switching cameras, enabling/disabling audio and video, and more. It also mentions additional resources for building applications with Agora SDKs and invites readers to join the Agora Developer Slack community.
