Media Meta Data Retrieval in Xamarin.iOS

Question

In my Xamarin.Forms app, I want to use a DependencyService for each platform to get meta data about local media files such as Height, Width and Rotation. Here is how I do it in Android:

public double ReturnVideoHeight(string mediaFilePath)
        {
            MediaMetadataRetriever reader = new MediaMetadataRetriever();
            reader.SetDataSource(mediaFilePath);

            var str = reader.ExtractMetadata(MetadataKey.VideoHeight);

            if (double.TryParse(str, out double num))
            {
                return num;
            }
            return -1;
        }

        public double ReturnVideoWidth(string mediaFilePath)
        {
            MediaMetadataRetriever reader = new MediaMetadataRetriever();
            reader.SetDataSource(mediaFilePath);

            var str = reader.ExtractMetadata(MetadataKey.VideoWidth);

            if (double.TryParse(str, out double num))
            {
                return num;
            }
            return -1;   

        }

        public string ReturnVideoRotation(string mediaFilePath)
        {
            MediaMetadataRetriever reader = new MediaMetadataRetriever();
            reader.SetDataSource(mediaFilePath);

            return reader.ExtractMetadata(MetadataKey.VideoRotation);
        }

I can't seem to find iOS libraries to accomplish the same thing. How could I go about this?
