This is stuff is such a PIA to parse. I assume it's just different teams doing different features over the years, and being alternately repulsed/seduced by each format. Probably features are implemented as libraries so there isn't a master oversight - they aren't trying to make iMessage's internal formats follow a consistent plan, just let all the libs coexist...

Maybe they should be repulsed, considering all of the journalists that are getting persecuted and/or murdered because they are getting pwned through iMessage serialization bugs :)

As someone who used to work on that team, it’s so interesting hearing thoughts from external public on the team.

I would love to hear your thoughts as an insider.
