Function to open apple maps for driving directions?

I am constructing an app that features a list of businesses and their locations (locations in coordinate form), and I'd like to provide a button that, when pressed, pushes the user over to Apple Maps and brings up driving directions.

How could I go about doing this? I've seen similar questions asked on StackOverflow, but they've been referring to mobile web URLS, mine will be native to the application.

Thanks!

Yes you can do this. Check out this code.

    let placemark : MKPlacemark = MKPlacemark(coordinate: <your coordinate>, addressDictionary:nil)
    //your placemark... Put in the coordinate here
    let mapItem:MKMapItem = MKMapItem(placemark: placemark)
    let launchOptions: NSDictionary = NSDictionary(object: MKLaunchOptionsDirectionsModeWalking, forKey: MKLaunchOptionsDirectionsModeKey)
    //in the lauch options, you can make it driving, walking, or public transportation
    MKMapItem.openMapsWithItems([currentLocationMapItem, mapItem], launchOptions: launchOptions as? [String : AnyObject])
