Connection Interrupted error in iOS simulators after updating to xcode 7 I have updated to Xcode 7 from App Store. And now when ever I run an application or directly start the simulator from Xcode, i got an error Error Returned in reply: Connection Interrupted. 



I searched on internet, but did not found any solutions. Kindly advice about this issue.
I had the same problem, and I found at the end that I had 2 simulator windows running at the same time. I close both of them and Xcode, and the problem was solved.
I didn't need to restart my machine.
