Xcode 9 itunesstored crashing loop after starting a simulator session

I am getting the same issue.

It seems that it only happens when there is more than one simulator open.

Also macOS 10.12.6 and XCode 9GM,

and iTunes 12.7, if that has anything to do with it.

The simulator doesn't actually stop working, as far as I can tell, but clicking on the notification produces the following:

Tried resetting the simulator, but keeps crashing.

This might be related to the known issue reported as a part of xcode 9.1 beta release note:

https://download.developer.apple.com/Developer_Tools/Xcode_9.1_beta/Xcode_9.1_beta_Release_Notes.pdf

Known issue: Simulator will sometimes crash when interacting with devices booted by other versions of Xcode. (33585584)

Workaround: shutdown booted devices from the command line with xcrun simctl shutdown booted

Not sure if the proposed workaround works. You may want to give it a shot.
