This will allow YouTubers to stream iOS games and apps on their iPhones directly to YouTube without having to use the standalone YouTube gaming app.
The screen-streaming feature has been available on Android for some time, but to implement it on iOS, YouTube needed to add support for the Apple ReplayKit API, which it has now done.
In addition to a feature for live streaming what's on the iPhone's screen, YouTube is also gaining lower latency streaming for better creator/watcher chat interactions and improved chat moderation tools.
YouTubers can quickly pause chat with a new keyboard shortcut and they can opt in to an automated chat moderation system that will cause YouTube to flag and hold potentially inappropriate messages until they can be reviewed.
YouTube says its new features are rolling out to users around the world today. The YouTube app can be downloaded from the App Store for free. [Direct Link]
