Xcode completions, spelling checkings stopped -

-

my xcode 4.3.2 stopped show spelling errors , completions code. way find out if there error in code - build it. xcode colores keywords such if, else, for etc. other code hasn't colored. shown few strange completions. example:

cgpoint p; p.y // completion "yes" p.x // completion "xor"

completions methods calls nearaly used methods. how can fix this? rebooted mac several times already, , didn't find stuff in xcode's preferences.

what solve issue is:

1.) change build settings llvm 3.1 gcc 4.2

enter image description here 2.) go organizer>projects>(select project)> delete derived data

3.) change builds settings llvm 3.1

enter image description here

my syntax highlighting works again. no need restart xcode, , jump through other hoops , hurdles.

hope helps me !

update: people can working step 2, if doesn't work. follow 3 steps.
