Can't get location right using Swift

So, I am trying to get my Location inside a function of my ViewController.swift.

The Code I use works when i try it like this:

import UIKit
import CoreLocation


class ViewController: UIViewController, CLLocationManagerDelegate {

    var manager : CLLocationManager!


    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view, typically from a nib.

        manager = CLLocationManager()
        manager.delegate = self
        manager.desiredAccuracy = kCLLocationAccuracyHundredMeters
        manager.requestAlwaysAuthorization()
        manager.startUpdatingLocation()
    }

    func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {

        var locValue : CLLocationCoordinate2D
        locValue = manager.location.coordinate
        println("Coordinates = \(locValue.longitude) + \(locValue.latitude)")
        manager.stopUpdatingLocation()
    }

But what I am trying to do is get it while pressing a button which toggles a function: 

var manager : CLLocationManager!
    override func viewDidLoad() {
        super.viewDidLoad()

        manager = CLLocationManager()
        manager.delegate = self
        manager.desiredAccuracy = kCLLocationAccuracyHundredMeters
        manager.requestAlwaysAuthorization()
        manager.startUpdatingLocation()
        }

    func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
        var locValue: CLLocationCoordinate2D = manager.location.coordinate
        println("locations = \(locValue.longitude) \(locValue.latitude)")
        manager.stopUpdatingLocation()
    }

    @IBAction func refresh() {
        getWeatherData()
        refreshButton.hidden = true
        acitivityIndicatorView.hidden = false
        acitivityIndicatorView.startAnimating()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
       }

        func getWeatherData() -> Void {

 func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]!) {
                var locValue: CLLocationCoordinate2D = manager.location.coordinate
                println("locations = \(locValue.longitude) \(locValue.latitude)")
                manager.stopUpdatingLocation()

While using a breakpoint i realized it gets to func locationManager but it jumps to the end of my getweatherdata() function.

I can't see why it doesn't work.

What you are doing is not possible. Inly thing you can do is call manager.startUpdatingLocation() inside refresh() and wait till didUpdateLocations get called with the updated location data.

@IBAction func refresh() {
    manager.startUpdatingLocation() 
    refreshButton.hidden = true
    acitivityIndicatorView.hidden = false
    activityIndicatorView.hidesWhenStopped = true
    acitivityIndicatorView.startAnimating()
}

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    var locValue: CLLocationCoordinate2D = manager.location.coordinate
    println("locations = \(locValue.longitude) \(locValue.latitude)")
    manager.stopUpdatingLocation()
    refreshButton.hidden = false
    acitivityIndicatorView.stopAnimating()

}
