XCode .dylib file missing. Solution not working

I am getting the following error in my iPhone application:

warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.3 (8J2)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found).

I found another stack overflow question which had a solution. So, I performed the following, as per that solution:

cd /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.3 (8J2)/Symbols

sudo ln -s .开发者_开发技巧./../4.3.3\ \(8J2\)/Symbols/Developer/ Developer

And, the terminal returns:

ln: Developer: File exists

So the file exists? Or doesn't? Why am I getting this error in my iPhone application?

If you are running your app on a device, simply try uninstalling your app from your device, then turning off your device, then back on again. It just worked for me. :)

Uninstall the app and/or reset simulator.
