I have a problem with running the open-live ios project.
I could build the project and I replaced the APP ID and token placeholder strings.
I run the project on 2 iPad devices one for the broadcaster and another one for a client.
When I get into the live streaming room with the same channel id as the broadcaster, it shows nothing which occurring "warning code: invalid view & warning code: 16"

I attached the screenshot.

Please check this image as well.
It is saying "Unable to simultaneously satisfy constraints". I think it is the main issue that it occurs invalid view and code 16.

@CodeWarrior1012 sorry for late reply. i'm not sure if we adapt to ipad at all. does it work well on your iphone?
The error you posted is just NSLayoutConstraint error for barbutton. it should not affect your video views
