XCode 8 Crashes when selecting capabilities tab for simulator build.

Hello,

I'm currently trying to work on a Unity game that is making use of some iOS app extensions, however when I go to the capabilities tab of my main iOS target all I see is a blank white section and after a few moments XCode crashes. This issue *only* happens when I set the target SDK to Simulator in Unity, it does not happen when I set it to Device.

I am using Unity 5.5.1p4 and XCode 8.2.1
