Cannot run on the selected

Answer 1

I had this issue after updating from Facebook SDK 3.1 to Facebook SDK 3.1.1. My fault, I guess.

Inside "resources" folder, now there is a totally useless but dangerous info.plist that, if imported, may break your project file. Don't know why they included it but I believe few of us made the same mistake recently.
