We've attempted to use the Photos framework to obtain a PHAsset and it works. However, it requires manually creating the user interface, which is not our preference.

PHFetchOptions *options = [[PHFetchOptions alloc] init];
options.predicate = [NSPredicate predicateWithFormat:@"mediaType = %d", PHAssetMediaTypeVideo];
PHFetchResult *assetsFetchResult = [PHAsset fetchAssetsWithOptions:options];
[assetsFetchResult enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
    PHAsset *asset = (PHAsset *)obj;
}];

We prefer to use PHPickerViewController. Unfortunately, it doesn't seem to work as expected. Instead of receiving a PHAsset type, we only obtained a file URL. The same error as mentioned below occurred: "FBSDKErrorDeveloperMessageKey=Must refer to an asset file".

PHPickerConfiguration *configuration = [[PHPickerConfiguration alloc] initWithPhotoLibrary:[PHPhotoLibrary sharedPhotoLibrary]];
configuration.selectionLimit = 1;
configuration.filter = [PHPickerFilter videosFilter];
PHPickerViewController *picker = [[PHPickerViewController alloc] initWithConfiguration:configuration];
if (@available(iOS 14, *)) {
    picker.delegate = self;
} else {
    // Fallback on earlier versions
}
[self presentViewController:picker animated:YES completion:nil];

//delegate
- (void)picker:(PHPickerViewController *)picker didFinishPicking:(NSArray<PHPickerResult *> *)results {
    [picker dismissViewControllerAnimated:YES completion:nil];

    for (PHPickerResult *result in results) {
        if (@available(iOS 14, *)) {
            NSItemProvider *itemProvider = result.itemProvider;
            NSString *assetIdentifier = result.assetIdentifier;
            [itemProvider loadFileRepresentationForTypeIdentifier:@"public.movie" completionHandler:^(NSURL * _Nullable url, NSError * _Nullable error) {
                NSLog(@"Selected video URL: %@", url);
                dispatch_async(dispatch_get_main_queue(), ^{
                    FBSDKShareVideo *vedio = [[FBSDKShareVideo alloc] initWithVideoURL:url previewPhoto:nil];
                    FBSDKShareVideoContent *vc = [[FBSDKShareVideoContent alloc] init];
                    vc.video = vedio;

                    FBSDKShareDialog *dialog = [FBSDKShareDialog dialogWithViewController:self withContent:vc delegate:self];
                    dialog.mode = FBSDKShareDialogModeNative;
                    [dialog show];
                });

            }];
        } else {
            // Fallback on earlier versions
        }
    }
}

I'm having the exact same issue (Must refer to an asset file.). All was previously working with ALAsset then stopped working (I'm not sure when). Running on latest 17.4.0 framework. Tried to change over to PHAsset and same issue. Then tried passing local file and same issue. Passing NSData has never worked. I am really surprised more people aren't elevating this. Please expedite fixing!!! Thank you :)

Maybe part of the issue is in the following not accounting for newer ph:// schema: https://raw.githubusercontent.com/facebook/facebook-ios-sdk/refs/heads/main/FBSDKShareKit/FBSDKShareKit/Content/ShareVideo.swift

Have this issue too, tried sharing ShareVideo(videoAsset: phAsset) which does open the Facebook app but there is no asset to share.

Using the url from AVURLAsset that was obtained using PHImageManager.default().requestAVAsset(forVideo: phAsset and ShareVideo(videoURL: avUrlAsset.url) also opens Facebook but there is no also asset.

The url has format file:///var/mobile/Media/DCIM/116APPLE/IMG_6683.MOV#YnBsaXN0MDDRAQJfEBtSZWNvbW1lbmRlZEZvckltbWVyc2l2ZU1vZGUQAAgLKQAAAAAAAAEBAAAAAAAAAAMAAAAAAAAAAAAAAAAAAAAr
