How to get URL for a PHAsset?

Question

I am using a third party library to select multiple images from the Photo Library. On selecting multiple images it returns an array of PHAsset objects. Now, I want to save the URL (or some reference) for these objects in the core data. But I do not know how to get the URL. Is there any other reference I could store in the core data which could help me in fetching the same image from the photo library?

I used @iMHitesh Surani answer and it worked perfect, I converted it into Swift 3.1 and put it into an extension of PHAsset in order to use that method everywhere, here it is:

extension PHAsset {

    func getURL(completionHandler : @escaping ((_ responseURL : URL?) -> Void)){
        if self.mediaType == .image {
            let options: PHContentEditingInputRequestOptions = PHContentEditingInputRequestOptions()
            options.canHandleAdjustmentData = {(adjustmeta: PHAdjustmentData) -> Bool in
                return true
            }
            self.requestContentEditingInput(with: options, completionHandler: {(contentEditingInput: PHContentEditingInput?, info: [AnyHashable : Any]) -> Void in
                completionHandler(contentEditingInput!.fullSizeImageURL as URL?)
            })
        } else if self.mediaType == .video {
            let options: PHVideoRequestOptions = PHVideoRequestOptions()
            options.version = .original
            PHImageManager.default().requestAVAsset(forVideo: self, options: options, resultHandler: {(asset: AVAsset?, audioMix: AVAudioMix?, info: [AnyHashable : Any]?) -> Void in
                if let urlAsset = asset as? AVURLAsset {
                    let localVideoUrl: URL = urlAsset.url as URL
                    completionHandler(localVideoUrl)
                } else {
                    completionHandler(nil)
                }
            })
        }
    }
}
