iOS/tvOS playground fails with "Unable to find execution service for selected run destination"

Question

After migrating to XCode 7.1 I can not use playground with iOS and tvOS platforms. Only OS X works. Simplest playground code produces error message:

Unable to find execution service for selected run destination

I suspect it has to do with XCode not finding the right simulator, however I have no idea where and how to configure it.

I tried playground in the existing project, as well as just newly created one from the splash screen.

Any ideas what might be wrong?

UPDATE:

Checking console gives a bit more insight, but still not clear how to fix:

Answer 1

There may be a faster solution:

Check that you have iPad Pro simulator in your devices in Xcode. If not – add it via Add Simulator option.

As some have noted in comments, you may also need to restart Xcode or reopen the playground.

To add a simulator go to Devices (Window > Devices). Click the + button at the far bottom left of the window, click "Add Simulator", then select the appropriate "Device Type" from the dropdown and click "Create".
