What MirekE said, except updated for Swift 3, Xcode 8.2:

DispatchQueue.main.async {
    self.table.reloadData() 
}

You are running table.reloadData() from a completion handler. The chances are that the code is not executed on the main thread. All UI stuff needs to be done on the main thread. Try forcing the reloadData to run on the main thread:

dispatch_async(dispatch_get_main_queue()) {
    self.table.reloadData()
}
