I don't get the downvotes. They are making the compiler. How hard can it be to do a proper decompiler? They have the binary; they have the source (in some wa

  Very hard. Like, this is the holy grail of security/reverse engineering.

If Apple was demanding the debugging symbol database, that’d be something else. But they aren’t.
