Hi, I've been using Xcode to write CoreAudio code recently, and it worked fine. Then one day, I get a message saying...

Uncaught Exception: ***-[NSCF String replaceCharacters inRange: with string:]:nil arguement

The stack backtrace has been logged to the console.

Then whenever I tried to open a xcodeproj. file I get a similar error, that includes "The stack backtrace has been logged to the console." Then, Xcode won't let me open and compile my xcodeprojects, or my cpp files.

I tried reinstalling Xcode twice and I still got the same errors. Does anyone know how to fix these problems? If so, I'd greatly appreciate it if you could respond asap.

Issues caused when opening xcodeproject files can sometimes be caused by corrupt project files. I have resolved this by creating a new project and importing all my source files from the previous project into the new project.

Did you recieve that error when you opened xcode or at run time?
