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 Product > Clean, the option is grayed out. When I look at the list of simulators, all I get is My Mac instead of the usually iOS Device. How do I get my simulators to come back?
Click on the project name (Right to the Run button). Three options will appear.
You can click on "New scheme" and then click on "OK" in popup window.
You will have simulators list back.
