Static Analysis on iOS
The preferred method of statically analyzing iOS apps involves using the original Xcode project files. Ideally, you will be able to compile and debug the app to quickly identify any potential issues with the source code.
Black box analysis of iOS apps without access to the original source code requires reverse engineering. For example, no decompilers are available for iOS apps (although most commercial and open-source disassemblers can provide a pseudo-source code view of the binary), so a deep inspection requires you to read assembly code.
