If I execute the following command ...
sudo xcrun xcscontrol --list-simulators
... the result is as follows ...
Found 0 total simulators
I guess that's why we cannot see any simulator in the bot configuration tab "Devices" if we choose "Test With: iOS - Specific iOS Devices", the dialog just shows "No devices found.". Most of the times anyways, sometimes if we leave the configuration dialog open for a very long time, a list of simulators suddenly appears - which is very strange.
However the "Devices" window of Xcode shows all Simulator Devices properly and so does the following command:
xcrun simctl list
Why is the Xcode CI system unable to find Simulator Devices on our system?
Is there any way to see a more verbose output of xcscontrol any why it seems to fail?
Don't know if this problem is related to the CouchDB problems of Xcode 8.3.2 described here: https://forums.developer.apple.com/thread/75581.
