title: iPhone Codesign object file format invalid or unsuitable
body: <p>I accidentally deleted my target in xcode.</p>
  
  <p>so i created a new one with the exact same name. in the target settings i again selected the proper codesigning identity</p>
  
  <p>but now i can't compile for the device anymore. as soon as i want to build, i get:</p>
  
  <pre><code>CodeSign build/Release-iphoneos/myApp.app
  ....somestuff....
  /Volumes/XCodeProj/myApp/build/Release-iphoneos/myApp.app: object file format invalid or unsuitable
  Connad /usr/bin/codesign failed with exit code 1
  </code></pre>
  
  <p>I already tried to clean targets.
  what could cause this problem and how to solve it?</p>
