Yo peeps there’s this thing called omlet arcade
It allows you to stream with iOS 11 complete with chat.
There’s also private chats like in discord, so this could be used as an alternative.
It’s free on the App Store (not sure about android users though, you can use mobizen life but you’d need to verify your YouTube channel to stream to YouTube)
But omlet allows you stream to any platform, twitch, the omlet arcade app, you name it.
You do need to activate your account for some features though (including creating a community)
Also if you wanna follow me on the app
My name in omlet is: raekko7
