Answer 1

As answered here this is a bug in the iOS simulator but is not a problem when running on the actual device. This bug persists at least through Xcode 4.4.1 and the iOS 5.1 SDK.

Answer 2

Remove the debugger breakpoints & re-run. This worked for me. Apparently the problem is working in iOS6 and should also be fine on the device.

Answer 3

Try add in your project a

Security.framework

CoreFoundation.framework

from Simulator folder
