Since Swift 1.2 (Xcode 6.3) "internal" symbols of Swift frameworks are given "hidden" C visibility to prevent them being accessed from outside the framework. This is a problem for programs like injectionforxcode which need to access these symbols when a class from the framework is "injected" by dynamically loading a new version of the class.

This binary reverses this hiding and takes a framework name followed by a list of object files to be patched to export any "hidden" symbols so they can be accessed in global scope by the run time loader. This is in preference to having to make the symbols public in the Swift source.

To use, build this project and add a "Run Script" build phase to the target that builds the framework just after linking that contains:

    UNHIDE=~/bin/unhide.sh
    if [ -f $UNHIDE ]; then
        $UNHIDE
    else
        echo "File $UNHIDE used for code Injection does not exist."
    fi

This will patch the object files of the framework project to export all symbols defined on the package and then re-link the framework executable. If it's necessary to link the framework with another framework copy the contents of the ~/bin/unhide.sh script into the "Run Script" build phase and edit the command that re-links the framework.
