Clearing Issue Navigator in Xcode 4

Question

While doing a big rework of my code, I accidentally built the project. Naturally, there was a whole bunch of errors. So now I have all these annoying error messages in my code.

How do I clear the Issue Navigator and get rid of them?

Answer 1

Product|Clean or ⌘+shift+k cleans the code.

Also you can visit the organiser and remove the build logs
