title: Multiple build commands warning while building - Objective C
body: <p>When I build my iPhone Project in XCode, I'm getting the following warning.</p>
  
  <pre><code>[WARN]Warning: Multiple build commands for output file /Users/SilentCoder/Library/Developer/Xcode/DerivedData/myProject-csfqcpziyuvhbiatwwjtkkmwbxwv/Build/Products/Debug-iphonesimulator/myProject.app/car.png
  </code></pre>
  
  <p>I don't understand what does that mean. I have made targets for both iPhone and iPad for my project.</p>
