Problem with UIImageWriteToSavedPhotosAlbum

Bắt đầu bằng cách tái hiện assertion từ saveToAlbum trong image-util.ios.ts với @nativescript/ios 7.2.0, sau đó so sánh cùng đoạn mã completionTarget của UIImageWriteToSavedPhotosAlbum với phiên bản 6.5.4. Issue được giải quyết khi completion callback hoạt động mà không có ClassBuilder assertion trong phiên bản mới hơn.

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);
