Maintain an accurate list of iOS simulators

When upgrading, you may drag around old simulators no longer available with your current version of Xcode. You can clean these by running this command in Terminal:

xcrun simctl delete unavailable

Quit Xcode first just for good measures. From the documentation:

Delete a device or all unavailable devices.
