Find contacts method crashes

[otymartin]

This crashes with libc++abi.dylib: terminating with uncaught exception of type NSException

 dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) {
            if let contacts = self.kpkContactStore.findContactsWithValidNumbersOnly() {
                self.contacts = contacts
                dispatch_async(dispatch_get_main_queue()) {
                    self.tableView.reloadData()
                }
            }
        }

It crashes when I run it in view did Load. FYI the view controller I load it in is for an xib.

Could you tell me which operating system you're running on?
