fyi - afro is using python's kaitai wrapper to read apple's apfs - would love to get this working with swift program if anyone is interested to collaborate. https://github.com/cugu/afro/tree/master/afro/libapfs

@mothlike - if we use the pythonscala template as a swift template
https://github.com/kaitai-io/kaitai_struct_compiler/blob/18cecf49a36446e6d0e2e3d98a00f1c346e7446a/shared/src/main/scala/io/kaitai/struct/languages/PythonCompiler.scala

-> swift

I'm happy to help / draft / refine this together to get the apfs.fsk file to parse out with this library.
https://github.com/cugu/afro/blob/master/afro/libapfs/apfs.ksy

I'm probably going to manually build this out tomorrow into swift file anyway.
I moved this to own repo - https://github.com/johndpope/kaitai-apfs-swift/

it seems there's one extra attribute hasattr that's used in this python file
https://github.com/cugu/afro/blob/master/afro/libapfs/apfs.py

(there's this old code that's attempting to port this function to swift
https://github.com/practicalswift/Pythonic.swift/blob/master/src/Pythonic.swift)

I threw this code up - it's just a skeleton right now (and needs camel casing). https://github.com/johndpope/kaitai-apfs-swift/blob/master/SwiftKaitai/SwiftKaitai/APFS.swift

any pointers would be appreciated on piggy backing off the kaitai_struct_swift_runtime

heads up - getting closer to having a worker apfs parser - https://github.com/johndpope/kaitai-apfs-swift. we should be able to cherry pick some of the code into /scala swift template generator.
