Why am I getting ibtool failed with exit code 255?

Question

All of a sudden I can\'t build my project. I get the following compiler error:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.pl

In my case, I was working on Visual Studio. It was all good. All of a sudden, I got the same issue. Then I opened XCode, I saw the updates available. Then I Updated the Xcode updates. Then it worked :)

So the reason was : XCode expected to complete some updates. Until that, It was not working properly.
