what member should I use in that situation?
let alertController = NSAlert(title: nil, message: "Place Not Found", preferredStyle: NSAlertFirstButtonReturn.Type)
the whole block:
if localSearchResponse == nil{
let alertController = NSAlert(title: nil, message: "Place Not Found", preferredStyle: NSAlertFirstButtonReturn.Type)
alertController.addAction(NSAlertDelegate(title: "Dismiss", style: NSAlertStyle.Default, handler: nil))
self.presentViewController(alertController, animated: true, completion: nil)
return
