    Being open source is technically not required to verify this. It’s possible to prove or disprove security claims by reverse engineering, and iOS specifically is already a popular t…

    All of the code is imported in 1 commit. The rest of the commits are deleting the specs that I guess were used to generate the code. There’s one commit adding code which explicitly…
