HELP: I can't delete a custom album with its photo using PHPhotoLibrary

App Development

I’m having hard time trying to figure out how to delete the custom albums made by my app along with its photos. NOTE: I can delete albums but not along with its photos.

THE CODE I’M BASING ON FROM STACKOVERFLOW: It works, but it deletes all the photos from the camera roll.

func deleteAllPhotos() {
let library = PHPhotoLibrary.shared()
library.performChanges({
let fetchOptions = PHFetchOptions()
let allPhotos = PHAsset.fetchAssets(with: .image, options: fetchOptions)
PHAssetChangeRequest.deleteAssets(allPhotos)
}) { (success, error) in
// Handle success & errors
}
}

MY MODIFIED CODE BASED ON THE ABOVE CODE:

let fetchOptions = PHFetchOptions()
fetchOptions.predicate = NSPredicate(format: “title = %@”, albumName)

    let assetCollections = PHAssetCollection.fetchAssetCollections(with: .album, subtype: .any, options: fetchOptions)
    let album: PHAssetCollection = assetCollections.firstObject!
    let allPhotos = PHAsset.fetchAssets(with: .image, options: fetchOptions)
    
    PHPhotoLibrary.shared().performChanges({
        guard let albumChangeRequest = PHAssetCollectionChangeRequest(for: (album)) else { return }
        let fastEnumeration = NSArray(array: [allPhotos])
                albumChangeRequest.removeAssets(fastEnumeration)
            }, completionHandler: { success, error in
            if success {
                print("removed")
            } else {
                print("not removed")
            }
        })

ERROR: Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: 'Unsupported predicate in fetch options: title == "albumName"
