Error Message in iOS Simulator

Hi Xamarin Team!

Since working with Xamarin on OS X Yosemite, the iOS Simulator can no longer be started. Xcode 5 and Xcode 6 beta are available and Xcode 5 is set as default using "xcode-select". When launching the iOS Simulator, the message in the attached screenshot is displayed. The error message reads (translated from German):

"Only a single instance of iOS Simulator can be running at a time"

In Console, the following messages are printed which indicate that Xamarin might be interfering:

04.09.14 23:16:13,734 mtouch-64[7088]: Bundle (null) does not have an FileProviderModuleClass entry.
04.09.14 23:16:13,796 com.apple.xpc.launchd[1]: (com.apple.xpc.launchd.domain.user.1025) Service "com.apple.iphonesimulator.109656" tried to hijack endpoint "PurpleFBServer" from owner: com.xamarin.monodevelop.188324
04.09.14 23:16:13,797 iPhone Simulator[7089]: Failed to check in PurpleFBServer service: 1100

Is this a known issue and is there anything that can be done about it? The Xamarin Forums did not prove to be very helpful on this issue.

Cheers, Ben

We have checked this issue on Yosemite 10.10 preview 7 with Xcode 5.1 and we are also experiencing the same issue, i.e. while launching the simulator the application does not get deployed to the simulator and an error pop-up appears.

A separate issue is already been reported for the same by the Xamarin team.
