I'm trying to run an app in the simulator but get this error message:

Unable to run app in Simulator
An error was encountered while running (Domain = FBSSystemServiceDomain, Code = 4)

Screenshot for error

I've not seen any previous references to this from googling around.

Its using XCode 6 Beta, the app is in Swift which links to a Obj-C static library. It runs fine on the device.

Any ideas?

Go to the iOS Simulator menu and select Reset Content and Settings.

Alternatively, you could quit and reopen the Simulator.
