title: Xcode project not showing list of simulators
body: <p>I open my project in Xcode 6.1. When I try to run the project, the button is grayed out. When I try to go to <code>Product &gt; Clean</code>, the option is grayed out. When I look at the list of simulators, all I get is <code>My Mac</code> instead of the usually <code>iOS Device</code>. How do I get my simulators to come back?</p>
