Running on Xcode 6.1 obfuscates system symbols #15

Closed pstasiak closed 9 years ago

When running obfuscation script on Xcode 6.1, my output file contains defines such as "NSObject", "self", "length", "isEqual" and some other names from iOS SDK. On Xcode 5 eveything works fine, application compiles and works as expected with generated preprocessor's directives. Have you got similar experience on latest Xcode?

We identified similar issue for Xcode 6.x and working on fix

We identified the problem: iPhone frameworks are no longer distributed as full libraries, but instead Xcode provides something named: DYLIB_STUB. These DYLIB_STUB doesn't contain Objective-C metadata only the information that such class does exist. As a workaround you can use iphonesimulator SDK to compile the application, obfuscate it using simulator's SDK and later recompile it for any architecture you need.
