I’m researching binary-level obfuscation techniques for iOS applications to better protect compiled code against reverse engineering.
Most discussions I’ve found focus on source-level obfuscation (e.g., symbol renaming in Swift or Objective-C), but I’m specifically interested in binary obfuscation after compilation.
The project I’m working on is a hybrid codebase using both Swift and Objective-C.
My questions are:
What techniques are commonly used for binary obfuscation in iOS apps?
Are there any practical or production-ready approaches that work at the binary level (e.g., Mach-O modification, instruction transformation, etc.)?
Are there any specific challenges or limitations when dealing with a mixed Swift + Objective-C codebase?
What are the risks involved (e.g., App Store rejection, runtime instability)?
How effective is binary obfuscation compared to source-level obfuscation in real-world scenarios?
I’m not looking for a specific tool, but rather general approaches, best practices, or real-world experiences—especially for apps that require strong protection against reverse engineering.
Any insights would be appreciated.
