Ionic emulate ios results in black screen after accepting new XCode agreement

I recently updated XCode. I also updated OSX to El Capitan.

Now I can’t emulate my ionic app in ios anymore.

Problem 1: Now I have to type sudo ionic emulate ios (before I didn’t need sudo)

Problem 2: When I emulate, the simulator launches and I get a completely black screen. The console outputs this error:

I have no idea what any of this means. Everyone on my team is having the same problem. Is the ionic team aware of this?

what plugin are you using?

xam8re, these are from package.json:
