        print("user latitude = \(userLocation.coordinate.latitude)")
        print("user longitude = \(userLocation.coordinate.longitude)")

        self.labelLat.text = "\(userLocation.coordinate.latitude)"
        self.labelLongi.text = "\(userLocation.coordinate.longitude)"
        DataBaseFunctions.sharedInstance.saveUserDetail(dataToInsert: userLocation)

This is in Swift-NOW, You can use Timer for didUpdateLocation with

locationManager = CLLocationManager()
locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation
locationManager.delegate = self
locationManager.startUpdatingLocation()
var timer = Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(self.updateLocation), userInfo: nil, repeats: true)

func updateLocation() {
    let location: CLLocation = locationManager.location
    // Your code
}

// MARK: - CLLocationManagerDelegate

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    // Your code
}
