Swift Shield

Don't use this tool for production apps. I gave up on keeping this tool updated because every Swift release breaks SourceKit in a different way. It's probably really broken and is only useful as a way for you to learn more about obfuscation and SourceKit. SwiftShield is a tool that generates random and irreversible encrypted names for your iOS project's types and methods (including third-party libraries). It uses Apple's SourceKit to mimick Xcode's indexing behavior, revealing a complete map of your project that is used to safely rename parts of your project. Reverse engineering iOS apps is relatively simple due to the fact that almost every single type and method name is exposed in the app's binary. This allows jailbreak tools like class-dump and Cycript to extract this information and use it to change the behavior of your app in runtime.
