PHAsset get original file name

Question

I wonder if there any way to get the original file name using PHAsset?

I use the following code to extract the file info.

   [[PHImageManager defaultMa

I had to modify my code because it started returning nonsense names. My solution was to pick the resource based on asset's mediaType and resource's type, but maybe there is something easier:

extension PHAsset {
    var primaryResource: PHAssetResource? {
        let types: Set

        switch mediaType {
        case .video:
            types = [.video, .fullSizeVideo]
        case .image:
            types = [.photo, .fullSizePhoto]
        case .audio:
            types = [.audio]
        case .unknown:
            types = []
        @unknown default:
            types = []
        }

        let resources = PHAssetResource.assetResources(for: self)
        let resource = resources.first { types.contains($0.type)}

        return resource ?? resources.first
    }

    var originalFilename: String {
        guard let result = primaryResource else {
            return "file"
        }

        return result.originalFilename
    }
}
