Fuzzing is not a magic trick, in the same way as invariants are not, and unit tests are not, and debugging is not.
All these techniques have degrees of mastery, and if applied carefully, and in combination, can save you a lot of grief.
Dumb fuzzing will not get you anywhere, same as dumb unit testing, and dumb debugging.
In this case, iMessage is particularly well suited for some smart fuzzing because all the attack vectors seem to involve smallish malicious attachment files.
