Filename for an image in Assets.xcassets

Question

How do I get the filename for an image stored in Assets.xcassets? I've an image named "default" in an "Avatars" folder in my xcassets. How do I get the filename for this image if possible?

I need the filename to send to a server.

Answer 1

Files from Assets.xcassets are compiled into a .car file by Xcode and have no individual filenames inside your app bundle.

See eg Analysing Assets.car file in iOS for details of how such a .car file looks like.
