The operation couldn’t be completed. (OSStatus error -600.) Cant run app in simulator

Question

Using XCode 6.3.1 , SDK 8.3

Suddenly my app stopped running in (any) simulator and Xcode throws error

The operation couldn’t be completed. (OSStatus error -600.)

Tried cleaning, reset content and setting and even restarting my Mac.

Is there anything I can do to run my app in simulator.

Answer 1

Just quit your iOS Simulator then reopen the simulator then build your source Now it will work.

Answer 2

• if you run on the simulator -> relaunch the simulator
• if you run on real device -> reconnect the device

Answer 3

I encountered this issue on a 9.1 simulator. I was able to successfully run my app after doing a CLEAN, switching to an 8.4 simulator, compiling (successfully) and then switching back to 9.1 and running.

Answer 4

Solved it just by restarting the computer. Don't know what it means, but it can be fixed that way! Cheers
