in Appcelerator Titanium

If after importing an Alloy project into Titanium Studio, none of the Run/Debug options are available (iPhone Simulator, Android Emulator, etc), then you need to do a simple config change to get Studio to recognize your Alloy project as such.

  1. Open the project in App Explorer, and go to Project > Properties
  2. In the left pane of the Properties window, select Project Natures
  3. Check the boxes next to Alloy and Mobile
  4. Select Alloy again, and click the box that says Make Primary

It should look like this:
