Problem with UIImageWriteToSavedPhotosAlbum

Hey there I encountered a problem when calling UIImageWriteToSavedPhotosAlbum with a completionTarget. This error does not appear if I use "@nativescript/ios": "6.5.4", instead of "@nativescript/ios": "7.2.0".

I also tried to use the Typescript Subclassing Syntax without any success.

Error:

Code Snippet:
This implementation is based on this post.

const CompletionTarget = (<any> NSObject).extend({
        'thisImage:hasBeenSavedInPhotoAlbumWithError:usingContextInfo:': function (image, error, context) {
            if (error) {
                console.log("on error", error);
            }
        }
    }, {
        exposedMethods: {
            'thisImage:hasBeenSavedInPhotoAlbumWithError:usingContextInfo:': {
                returns: interop.types.void,
                params: [UIImage, NSError, interop.Pointer]
            }
        }
    });
    const completionTarget = CompletionTarget.alloc().init();
    UIImageWriteToSavedPhotosAlbum(imageSource.ios, completionTarget,'thisImage:hasBeenSavedInPhotoAlbumWithError:usingContextInfo:',null);

Calling UIImageWriteToSavedPhotosAlbum without a completionTarget works fine.
UIImageWriteToSavedPhotosAlbum(imageSource.ios, null, null, null);

  }

Comienza reproduciendo la assertion de saveToAlbum en image-util.ios.ts con @nativescript/ios 7.2.0 y, a continuación, compara el mismo código de completionTarget de UIImageWriteToSavedPhotosAlbum con la versión 6.5.4. El issue se resuelve cuando el callback de finalización funciona sin la assertion de ClassBuilder en la versión más reciente.
