didEnterRegion didExitregion not being called - ibeacon

Question

I am putting together a simple estimote test using swift and coreLocation. However I am not getting didEnterRegion, didExitRegion
I read following answers already but it still didn't end my problem.
startMonitoringForRegion never calls didEnterRegion/didExitRegion
locationManager:didEnterRegion not called when a beacon is detected
I added Background modes (Location updates)
I get the "didStartMonitoringForRegion" log in the output but then don't get any didenter or exit. I tried to walk out of house with beacon and back in but no luck. Ranging however works.
var locManager: CLLocationManager = CLLocationManager()
let iceRegion: CLBeaconRegion = CLBeaconRegion(proximityUUID: BEACON_PROXIMITY_UUID, major: BEACON_ICE_MAJOR, identifier: "ice")
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
if locManager.respondsToSelector("requestAlwaysAuthorization") {
locManager.requestAlwaysAuthorization()
}
if (self.deviceSettingsAreCorrect())
{
iceRegion.notifyOnEntry = true
iceRegion.notifyOnExit = true
iceRegion.notifyEntryStateOnDisplay = true
locManager.delegate = self
locManager.startMonitoringForRegion(iceRegion)
locManager.startRangingBeaconsInRegion(iceRegion)
}
}
func locationManager(manager: CLLocationManager!, didStartMonitoringForRegion region: CLRegion!) {
println("didStartMonitoringForRegion");
locManager.requestStateForRegion(region);
}
func locationManager(manager: CLLocationManager!, didEnterRegion region: CLRegion!) {

case .Outside:
println("BeaconManager:didDetermineState CLRegionState.Outside");

func locationManager(manager: CLLocationManager!, didRangeBeacons beacons: [CLBeacon]!, inRegion region: CLBeaconRegion!) {
