I made an extension for messages, and when I run it on the iOS simulator, everything does not work. When I try to run it on my phone, it compiles and says that it works for about 5 seconds before the crash and gives me a message about surfacing in Xcode, saying Could not attach to pidHere is a screenshot:

I use Xcode 8 beta 4 with iOS 10. Everything works fine in the simulator, it is on a physical device. I rebooted and restarted everything. I even tried on two phones. Does anyone know a solution?
