Q:

Error converting CLLocationCoordinate2D to CLLocation in Swift

I am trying to convert a cllocationcoordinate2d into a cllocation.  I get the error "Expected expression in container literal" on line 12 of the code below.   I also get the error "Cannot convert value of type cllocationcoordinate2d into expected value cllocation" on line 13 but that is because line 12 isn't working correctly. 
@IBAction func makeEvent(sender: UIButton)
    {
        let center = CLLocationCoordinate2D(latitude: loc1.coordinate.latitude, longitude: loc1.coordinate.longitude)
        let lat: CLLocationDegrees = center.latitude
        let long: CLLocationDegrees = center.longitude
        self.pointAnnotation1 = MKPointAnnotation()
        self.pointAnnotation1.title = "Event"
        self.pointAnnotation1.coordinate = CLLocationCoordinate2D(latitude: lat, longitude: long)
        self.pinAnnotationView = MKPinAnnotationView(annotation: self.pointAnnotation1, reuseIdentifier: nil)
        self.mapView?.centerCoordinate = self.pointAnnotation1.coordinate
        self.mapView.addAnnotation(self.pinAnnotationView.annotation!) 
        CLLocation *center = [[CLLocation alloc] initWithLatitude:latt longitude:longg]
        eventRecord.setObject(center, forKey: "event")
        let publicData = CKContainer.defaultContainer().publicCloudDatabase
        publicData.saveRecord(eventRecord) { record, error in
        }
        if error == nil
        {
            print("Location saved")
        }
        loadEvent(){ (error, records) in
            if error ! = nil {
                print("error fetching locations")
            } else {
                print("Found Event")
            }
        }
    }

A:

You are mixing up objective c and swift. 
Try this:
    let center = CLLocation(latitude: lat, longitude: long)

Instead of:
    CLLocation *center = [[CLLocation alloc] initWithLatitude:latt longitude:longg]
