I have AppCode 3.1.6 & Xcode 6.3.2. I can successfully edit & build my Xcode project in AppCode, but I can't run it in the iOS Simulator. I don't even see it in the list. I've tried manually starting the simulator then starting AppCode & I still don't see it in the list.
FYI, I can run the app just fine in the iOS Simulator from Xcode.
