Warning while compiling code on ios device

I am getting this warning while compiling my code on ipad.

warning: Unable to read symbols for /Develope开发者_如何学编程r/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib

Any Idea as what symbols it is referring to.

XCode4 is still under NDA right? You will find an answer to this specific issue over at Apple's developer forums.

This is not something you need to worry about.
