XPC connection interrupted in Xcode 7 for iOS 9

XPC connection interrupted
_BSMachError: (os/kern) invalid capability (20)
_BSMachError: (os/kern) invalid name (15)

Since XPC means OS X interprocess communication, so I think this can solve the problem, 

dispatch_async(dispatch_get_main_queue(), ^{
    // do what you want to do.
});
