Swift - CLLocationManager not asking for user permission

Question

I am with Xcode beta 2 and trying to get user location with OS X app, however it is not even asks user permission. here is what I did until now.

...
import CoreLocation

class AppDelegate: NSObject, NSApplicationDelegate, CLLocationManagerDelegate  {

    var locManager : CLLocationManager = CLLocationManager()

    func applicationDidFinishLaunching(aNotification: NSNotification?) {
        locManager.delegate = self
        locManager.desiredAccuracy = kCLLocationAccuracyBest
        locManager.startUpdatingLocation()
    }

    func locationManager(manager: CLLocationManager!, didUpdateToLocation newLocation: CLLocation!, fromLocation oldLocation: CLLocation!) {
        //doSomething.
    }

}

nothing happens. I looked other questions and try all suggested solutions from answers but did not work. Tried with Objective-C, all fine. Am I missing something here?

Location Service enabled on preferences of the computer. Also "NSLocationUsageDescription" is in info.plist. NSLocationWhenInUseUsageDescription and NSLocationAlwaysUsageDescription for 10.10 and later, I am working on 10.9.

There were no problem code wise, just noticed it is App Sandbox entitlement problem. Once I have checked Location under App Data it worked right away.
