Simulator not running after upgrading to Sierra (Mac OS 10.12)

After upgrading to Mac OS Sierra (10.12) I'm finding that the Simulator doesn't run. I can see the icon briefly appear before it then disappears. In Eclipse I get the below output:

Attempt 1 to connect to simulator...

Couldn't connect to simulator.

In the apple console logs I see this message:

Sep 21 21:12:16 macbookpro com.apple.xpc.launchd[1] (com.garmin.connectiq.simulator.1316[2432]): Service exited with abnormal code: 255

Anyone else experiencing this?

We haven't ran the simulator on Sierra yet, so I'm not sure if it'll work or not. Let me see about getting one of our Macs upgraded to see what happens.

I also upgraded to Sierra and luckily, I can still run my widget in the simulator.

My environment:

Macbook Pro 15" 2011
Eclipse Mars
Connect IQ 2.1.3

We've tested this (Eclipse Neon on OS X 10.12), and are unable to reproduce the issue. See if you can launch the simulator yourself outside of Eclipse. It's located in <connectiq-sdk-directory>/bin/ConnectIQ. Just double-click that, and the sim should open. Perhaps the simulator app is corrupted and won't launch. In that case, I'd recommend re-downloading the SDK.
