Issue with Xcode 9.0 Simulator

[hlowe]

Thanks for posting this Panos.

I made another attempt to revert back to Xcode 9.0.1 today with no luck. On
my machine, at least, the process of installing an iOS app onto the
simulator is completely broken.

I archived Xcode 9.1 and restored Xcode 9.0.1 from a Time machine backup
(also later reinstalled a fresh version of 9.0.1 from Apple).

Using LC 8.1.7 Stable under Mac OS 10.13.1 and Xcode 9.0.1 the only way that
I can get LC to install and launch an iOS app in the simulator is to
manually restart the simulator device while LC is attempting to launch the
app on the simulator. Most of the time even this doesn't work and LC hangs
(with a spinning 'beachball' cursor) requiring that a force quite and
restart. On the rare occasions that the app installed, it works fine.
Unfortunately this leaves the "Standalone Builder Progress" window open
reporting "Launching App…". If I then quite LC, relaunch it and then select
the "test" menu item to try to install the app again, LC crashes (suddenly
quits). Crash Log excerpt below.
