Today I noticed there was a new section in settings that showed up on my iPhone. It wasn't there before I updated to 9.3. I do have the developer beta profile installed on my iPhone and iPad, but it only shows up on my iPhone. Is this something to do with Xcode? I was messing around in Xcode the other day, and I did have my iPhone plugged into my computer, but I didn't do anything in Xcode that would affect my iphone. Looks pretty interesting, but I've never seen it before. Can anybody explain this?
