ld: 3 duplicate symbols for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation) Help?

Just on the Blog Reader project, at the Handling Malformed Data video.

I did a very small amount of experimenting with my code (as thats how you learn) but it didn't work and I was given this error then put everything back as it was (and checked) and still getting the same error. The breakpoints are not showing anything either.

Now getting this error: "ld: 3 duplicate symbols for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)"

did you by chance import any of the project files provided by treehouse into your project in order to reverse what you had done?

usually this means you have a duplicated class etc in your project somewhere. is there more to that error code? Did you accidently import a .m file instead of a .h somewhere?. Also, do you have any variables named Id in the project?. also check your build phases in your target. If there are any duplications it will throw this error so see if you have multiple items with the same name in your build phases. When I saw this error it was because I had accidently imported part of another xcode project into mine and had 2 main methods. It showed up as a duplicate in build phases and I deleted one and it worked. But there are lots of scenarios that will throw this error so it could be many things.

what was it that was actually throwing the error out of curiosity?
