I've updated to Xcode 10 GM, removed the Xcode 10 beta but for some reason none of the simulators ever start. After waiting for awhile, I get this error:

The operation couldn’t be completed. (DVTCoreSimulatorAdditionsErrorDomain error 0.)

What does that mean and how do I solve this?

So, apparently the only solution is to restart your Mac

There are many possible solutions for this:

  1. Quit simulator (shortcut: cmd + Q) and try again

  2. Reset simulator content. Select Simulator. Goto Hardware tab -> Erase All Content and Settings...

OR

Run xcrun simctl erase all  command in terminal.

  1. Restart you Mac machine

Solution 2 worked for me!
