Error when running command to extract .car contents to folder

some 3x picture not have

This tool can't extract AppIcon.

Instead of:

for (NSNumber *scaleFactor in @[@1, @2, @3])
{
    CUINamedImage *image = [catalog imageWithName:key scaleFactor:scaleFactor.doubleValue];

    if (image && image.scale == scaleFactor.floatValue) [images addObject:image];
}

I tried simply:

[images addObjectsFromArray:[catalog imagesWithName:key]];

In my one test, this added 23 images to the array, which are of type CUINamedMultisizeImageSet.h , which doesn't respond to -size, and therefore crashes on CGSizeEqualToSize(image.size, CGSizeZero). Looks like this type is new in iOS 11 (it's not present in the iOS 10 runtime headers).

So if we want to make this work we'll have to add support for this type.

Assertion failed:

i can't extract all pictures from assets.car which is packaged by xcode 9

Any idea how @3x assets are stored? It seems naively looking for assets with a scale factor of 3.0 for the .kCoreThemeIdiomPhone does not work: mono0926@427dbd8

[catalog setValue:facet forKey:@"_storageRef"];

I'm trying to extract my Assets.car here. The tool gives me the following output but does not generate any data on disk. Shouldn't I find the contents in my "tmp" folder?
The assets file is from a tvOS project, in case that matters. If you'd like to have it for analysis, I can send it to you.
