I've used CodeRunner (http://krillapps.com/coderunner) for a long time but recently I can't compile any Objective-C code in it. I think this started happening around the time I updated to Xcode 5.1. I can still compile and run as normal in Xcode.

When I try to run in CodeRunner, the following error is printed.

clang: error: unknown argument: '-finput-charset=UTF-8' [-Wunused-command-line-argument-hard-error-in-future] clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

I've tried searching for what this error means but I can't find much. Has anyone got any ideas of what this might be?

Thanks in advance.

Thanks a lot! Any idea as to what the problem was?
Actually what the output says, after updating XCode clang treated unknown params as errors, which stopped compilation. This param must have been in there for a long time unnoticed.
