xcode4 templete does not have auto-complete code suggestion

I have downloaded the lastest version, and install the xcode4 templete, but the auto-complete in xcode4 editor does not work correctly, some classes’s object have code suggestion while some don’t. Fox example, CCAction and its sub class have code suggestion, CCNode and its sub class (like CCSprite) don’t have code suggestion.

I tried clean ~/Library/Developer/Xcode/DerivedData folder, the problem is still there
While the old project from old templete works fine with code complete
Should anything can set to solve this ?
thanks in advanced!

This bug is reported from different users. But I’m very sorry that it’s a bug of xcode4.0.2
I try to reproduce it, and found sometimes it works well and sometimes wrong.
It’s said that xcode4.2 has fixed this bug. Please update your xcode, wish you a good luck.

thanks for replay
i have downloaded xcode 4.2 beta and it works:)
