How to get co-ordinates from address(with postcode) Swift - IOS?

Question

I have a list of addresses with postcodes, which I need to display on a map (pin point).

So far I know to use co-ordinates to show pin points on map with core-location framework. Is there any other way of doing it? Like getting co-ordinates from address or use address to show pin points on map?

The main purpose is to calculate distances between locations.

Please guide me here. Thanks

To create an annotation from an address you need to use CLGeocoder's method geocodeAddressString:

let address = "5th Avenue, New York"
let geocoder = CLGeocoder()
geocoder.geocodeAddressString(address) { (placemarks, error) in
    if let placemarks = placemarks {
        if placemarks.count != 0 {
            let annotation = MKPlacemark(placemark: placemarks.first!)
            self.mapView.addAnnotation(annotation)
        }
    }
}

If you only want to get the coordinates for the location:

...
        if placemarks.count != 0 {
            let coordinates = placemarks.first!.location
        }
...

Here is the simple code snippet that shows how to show the pin on the map for the given array of address.

let geocoder:CLGeocoder = CLGeocoder()


for eachAddress in addressArray {
    geocoder.geocodeAddressString(eachAddress) { (placemarks:[CLPlacemark]?, error: NSError?) -> Void in
    //Assuming it has the data without any error
    let placemark = MKPlacemark(placemark: (placemarks?.first)!) 
    self.mkMapView.addAnnotation(placemark)
    }
}
