When I try launching the simulator from Xcode 9 it is unusably slow. Animations that would typically be done in a fraction of a second take up to 5 seconds to run.
Tried upgrading to the latest version of Xcode (9.1 9B55) and I'm still having the issue.
I'll ask the obvious question. Do you have the simulator's Slow Animations debugging feature on (Cmd-T)?
Yes, common issue - feel your pain - search here for other threads...lots of comments about Xcode 9's performance.
There may be things you can do that will help the simulator in particular, depending on your app(s). See:

Still no joy, give the latest Xcode 9.2 beta a shot.
Good luck.
That was it. Thank you
