Encoding Verification

As a further step toward ensuring 64-bit capable code, you can run a script that verifies the consistency of old-style (unkeyed) archiving code. This script, named CoderFormatVerifier, is installed in /Developer/Extras/64BitConversion/.

The script replaces NSCoder method invocations with type-checked function calls. On the command line, pass the script a directory—it should be copy of your source directory. The script recursively modifies all the .m and .M files in-place and then writes the function prototypes to standard output (stdout). You can then copy and paste the function prototypes into your prefix header, compile the code, and then inspect any compiler errors that you get. (Link errors are expected because the script only generates function prototypes.) Run the script without any arguments for usage information.
