swift - Why i can't get Location? -

i want location coordinates. , reason loactionmanger:didupdatelocations not work. hope can help.

import corelocation class location: nsobject , cllocationmanagerdelegate {     let locationmanager = cllocationmanager()     var latitude = 0.0     var longitude = 0.0     func getlocation() -> (latitude:double , longitude: double ){         if(cllocationmanager.locationservicesenabled()){             locationmanager.delegate = self             locationmanager.desiredaccuracy = kcllocationaccuracykilometer             locationmanager.requestwheninuseauthorization()             locationmanager.requestalwaysauthorization()             locationmanager.startupdatinglocation()         }         return (latitude, longitude)     }     func locationmanager(manager: cllocationmanager!, didupdatelocations locations: [anyobject]!) {         var location :cllocationcoordinate2d = manager.location.coordinate         latitude = location.latitude         longitude = location.longitude         println("location: latitude: \(latitude)")         println("location: longitude: \(longitude)")         locationmanager.stopupdatinglocation()     }     func locationmanager(manager: cllocationmanager!, didfailwitherror error: nserror!) {         println("error while updating location" + error.localizeddescription)     } } 

here example works. check various authorizations , errors framework can return.

one thing keep in mind: object implementing cllocationmanagerdelegate needs retained. object gets deinit, goes delegate call stop.

usage: ctor create object, call startobserving() , stopobserving() in client if stream location data in delegate method (streaming code not provided). use getcurrentlocation() 1 time value.
