body: <p><a href="https://developer.apple.com/library/prerelease/mac/releasenotes/General/APIDiffsMacOSX10_11/Swift/CoreLocation.html" rel="noreferrer">https://developer.apple.com/library/prerelease/mac/releasenotes/General/APIDiffsMacOSX10_11/Swift/CoreLocation.html</a></p>
  
  <p>shows that there were a couple of changes </p>
  
  <pre><code>func geocodeAddressString(_ addressString: String!, completionHandler completionHandler: CLGeocodeCompletionHandler!)
  </code></pre>
  
  <p>to:</p>
  
  <pre><code>func geocodeAddressString(_ addressString: String, completionHandler completionHandler: CLGeocodeCompletionHandler)
  </code></pre>
  
  <p>my code was:</p>
  
  <pre><code>var geocoder = CLGeocoder()
  
  geocoder.geocodeAddressString("\(event!.street), \(event!.city), \(event!.country)", completionHandler: {(placemarks: [AnyObject]!, error: NSError!) -&gt; Void in
      if let placemark = placemarks?[0] as? CLPlacemark {
          self.event!.lat = placemark.location!.coordinate.latitude
          self.event!.long = placemark.location!.coordinate.longitude
  
          self.event!.getMiles(self.currentLocation!.location!.coordinate.latitude, clong: self.currentLocation!.location!.coordinate.longitude)
          var mile = self.event!.miles != nil ? NSString(format: "%.1f miles", self.event!.miles!) : "Location services off"
          self.milesButton.setTitle(mile as String, forState: .Normal)
      }
  })
  </code></pre>
  
  <p>tried:</p>
  
  <pre><code>var geocoder = CLGeocoder()
  let address = "\(event!.street), \(event!.city), \(event!.country)"
  geocoder.geocodeAddressString(address, completionHandler: {(placemarks: [CLPlacemark]) in
       let placemark = placemarks[0]
       self.event!.lat = placemark.location!.coordinate.latitude
       self.event!.long = placemark.location!.coordinate.longitude
       self.event!.getMiles(self.currentLocation!.location!.coordinate.latitude, clong: self.currentLocation!.location!.coordinate.longitude)
       var mile = self.event!.miles != nil ? NSString(format: "%.1f miles", self.event!.miles!) : "Location services off"
       self.milesButton.setTitle(mile as String, forState: .Normal)
  })
  </code></pre>
  
  <p>it just keeps saying that its not allowed.  tried a few different combinations. this is do to the latest update to xcode / swift</p>
  
  <p>thanks in advance</p>
