fetch a list of photo albums

Hello everyone, I am trying to fetch a list of photo albums from the photo library and present it to the user to select one of them. I have the following code below which fetches the list of photo albums. I can see all the photo albums list in the output on xcode but it's not presenting to the user. How can I get it to present to the user?

func getPhotosFromAlbum(albumName: BeenThereItem)
            {
                var photoLibraryImages = [UIImage]()
                var photoLibraryAssets = [PHAsset]()
                let finalPhotos = albumName.photoAlbum

                DispatchQueue.global(qos: .userInteractive).async
                {
                    let fetchOptions = PHFetchOptions()
                    fetchOptions.predicate = NSPredicate(format: "mediaType = %d", PHAssetMediaType.image.rawValue)

                    let smartAlbums = PHAssetCollection.fetchAssetCollections(with: .smartAlbum, subtype: .any, options: nil)
                    let customAlbums = PHAssetCollection.fetchAssetCollections(with: .album, subtype: .any, options: nil)

                    [smartAlbums, customAlbums].forEach {
                        $0.enumerateObjects { collection, index, stop in

                            let imgManager = PHImageManager.default()

                            let requestOptions = PHImageRequestOptions()
                            requestOptions.isSynchronous = true
                            requestOptions.deliveryMode = .highQualityFormat

//                            let photoInAlbum = PHAsset.fetchAssets(in: collection, options: fetchOptions)
                            let photoInAlbum = PHAsset.fetchAssets(in: collection, options: fetchOptions)

                            if let title = collection.localizedTitle
                            {
                                if photoInAlbum.count > 0
                                {
                                    print("\n\n \(title) --- count = \(photoInAlbum.count) \n\n")
                                }

                                if title == albumName.photoAlbum
                                {
                                    if photoInAlbum.count > 0
                                    {
                                        for i in (0..<photoInAlbum.count).reversed()
                                        {
                                            imgManager.requestImage(for: photoInAlbum.object(at: i) as PHAsset , targetSize: CGSize(width: 150, height: 150), contentMode: .aspectFit, options: requestOptions, resultHandler: {
                                                image, error in
                                                if image != nil
                                                {
                                                    photoLibraryImages.append(image!)
     photoLibraryAssets.append(photoInAlbum.object(at: i))
                                                }
                                            })
                                        }
                                    }
                                }
                            }
                        }
                    }
                }
            }
