so Objective-C and Swift, many people
understand these languages.
The issue is, the tools that we use for reversing Malware
aren't really supportive of these languages.
It is more difficult. You really need
a live or jailbroken device.
So where this says live, if you have a jailbroken device,
and you're leveraging [? RTX, ?] you
could possibly pull the files through that way as well.
Just keep in mind, understanding the Malware,
decompiling it may be difficult. So you
may want to do dynamic analysis and watch it in action.
