Xcode Generic iOS Device but no Emulators
<p>I generated a build on an app for the App Store awhile back. Now I am making some changes but when I try to Run the app in Xcode v7.3.1 I see an alert saying "A build only device cannot be used to run this target. No supported iOS devices are available. Connect a device to run your application or choose a simulated device as the destination."</p>

<p>I can build the app and run it on my iPhone but my emulators have disappeared from the dropdown list of run targets.</p>

<p>I tried cleaning the build and setting Build Settings > iOS Deployment Target to 7.1 as suggested by others but to no avail.</p>

<p>How can I can get my emulators back in the list of run targets?</p>
