Getting the URL of picture taken by camera with Photos Framework

UPDATE: Seems like I found an answer to this Problem.

Step 1: I save the image to the camera

UIImageWriteToSavedPhotosAlbum(image.image, self, #selector(cameraImageSavedAsynchronously), nil)

this is done asynchronously, so make sure to set a selector when operation has finished.

Step 2: When operation has completed, I do the following:

func fetchLastImage(completion: (localIdentifier: String?) -> Void)
{
    let fetchOptions = PHFetchOptions()
    fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
    fetchOptions.fetchLimit = 1

    let fetchResult = PHAsset.fetchAssetsWithMediaType(.Image, options: fetchOptions)
    if (fetchResult.firstObject != nil)
    {
        let lastImageAsset: PHAsset = fetchResult.firstObject as! PHAsset
        completion(localIdentifier: lastImageAsset.localIdentifier)
    }
    else
    {
        completion(localIdentifier: nil)
    }
}

I fetch the last image in camera roll with PHAsset and save the local identifier of the image. This is not an URL, but a unique identifier which does not change. This way, you can access the saved image perfectly.

Hope this helps others!
