UIImagePickerControllerOriginalImage is not working in ios 11.2.1

In what cases will I be sad? if I have set allowEditing as false.

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    if let selectedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        // I am happy :)
    } else {
        // I am sad :(
    }
    dismiss(animated: true, completion: nil)
}

(I got a crash in iOS 11.2.1 iPhone SE(as per Crashlytics), so confused if there are legit conditions where this can fail or it is just an iOS bug.)

I ended up using this:

import Photos

extension UIImage {
    static func from(info: [String : Any]) -> UIImage? {
        if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
            return image
        }

        var imageToBeReturned: UIImage?
        if let url = info[UIImagePickerControllerReferenceURL] as? URL,
            let asset = PHAsset.fetchAssets(withALAssetURLs: [url], options: nil).firstObject {
            let manager = PHImageManager.default()
            let option = PHImageRequestOptions()
            option.isSynchronous = true
            manager.requestImage(for: asset, targetSize: CGSize(width: 1000, height: 1000), contentMode: .aspectFit, options: option, resultHandler: {(image: UIImage?, info: [AnyHashable : Any]?) in
                imageToBeReturned = image
            })
        }
        return imageToBeReturned
    }
}

In this way-

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    if let selectedImage = UIImage.from(info: info) {
        // I am happy :)
    } else {
        // I am sad :(
    }
    dismiss(animated: true, completion: nil)
}

This is working for me, please do suggest any improvements :)
