Every time I try to build this project after I change anything I get 2 errors of the form: illegal expression, found 'unknown' referencing both lines in updateColor() Here is some output: CompileC /Users/chrisg/Projects/ColorMeter/build/intermediates/ColorMeter.build/Objects/ppc/Controller.o Controller.m:52: illegal expression, found `unknown' Controller.m:54: illegal expression, found `unknown' cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode Controller.m: In function `-[Controller updateColor]': Controller.m:53: warning: cannot find class (factory) method. Then if I click the hammer again, it builds fine. Any clue what's going on here?

Showing messages 1 through 2 of 2.

  You are getting these errors because you copied the code from the page and this caused some invisible control characters to get copied into project builder which you can't see. Try deleting what was copied on the line you get the error and manually typing the code in.

  That did the trick!
  It's strange that clicking the hammer again would work.
  
  I think I'll suggest that Apple change the error message from 'unknown' to 'illegal token'.
