After causing many fans to lose hope, YouTube today released Version 11.10 with support for Slide Over and Split View.
By selecting YouTube from the slide over menu, YouTube will now play videos in a small window in Slide Over, while increasing in size when used in Split View.
All in all, it works about as expected – you can browse, visit channels, and watch videos from either option. Although it may have taken too long to get here, YouTube’s latest update is finally updated to support iOS 9’s features.
