/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/dyld_sim is not owned by root

I used this command on terminal:

sudo chown root /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/dyld_sim

This command change the ownership of the file dyld_sim to the root.
