Cannot get URL for photo saved to PhotosAlbum in Swift

I'm very green when it comes to Swift, and I'm just trying to get the file URL for a photo I've saved. Below is a small snippet inspired from this StackOverflow question

let imageData = AVCaptureStillImageOutput.jpegStillImageNSDataRepresentation(imageDataSampleBuffer)
// Save the photo to the album library
let image = UIImage(data: imageData)!
let orientation = ALAssetOrientation(rawValue: image.imageOrientation.rawValue)!
ALAssetsLibrary.writeImageToSavedPhotosAlbum(image.CGImage, orientation: orientation, completionBlock: {
                                             (url: NSURL!, error: NSError!) -> Void in
    if error != nil {
        print(error)
    } else {
        // We have the URL here
    }
})

However, I can't for the life of me get it to build. It's showing the following error:

Cannot invoke 'writeImageToSavedPhotosAlbum' with an argument list of type '(CGImage?, orientation: ALAssetOrientation, completionBlock: (NSURL!, NSError!) -> Void)'

And it's stating it expects:

Expected an argument list of type '(CGImage!, orientation: ALAssetOrientation, completionBlock: ALAssetsLibraryWriteImageCompletionBlock!)'

The one obvious issue I can see that's off is the CGImage parameter, but I have no clue how to change this, or if that's the only issue. Has anyone seen this or see what my rookie mistake here is?

You have an optional image.CGImage, the error says that you must unwrap it.

This should work.

let library = ALAssetsLibrary()
library.writeImageToSavedPhotosAlbum(image.CGImage!, orientation: orientation, completionBlock: {
    url, error in
    if error != nil {
        print(error)
    } else {
        // We have the URL here
    }
})

The new Photos.framework does provide the functionality you're looking for. Here's the link to the developer library containing relevant parts to what you're trying to do.
