Can't run ANYTHING on iOS. No error messages!

Hi guys, I've been trying to get Unity and Xcode all set up today and am trouble. I downloaded my certificates, made a provisioning profile and tried everything I could think of. I edited the player settings in Unity appropriately. However, when I attempt to run anything I only get a loading screen. Even a simple scene with only a camera and a cube with no lighting will not run. I get no error messages in Xcode or anything. Any suggestions?
