title: "clang: error: cannot specify -o when generating multiple output files" during Swift iOS build
body: <p>I just installed an additional dependency (HockeyAppSDK) using CocoaPods for my Swift iOS project and now my project fails during build giving me the error:</p>
  
  <blockquote>
    <p>clang: error: cannot specify -o when generating multiple output files</p>
  </blockquote>
  
  <p>I uninstalled the dependency and the project still fails during build with the same error. Any ideas on how to fix this? </p>
  
  <p>EDIT: 
  When building using the xcode cli the errors looks like:</p>
  
  <p>2015-07-24 20:28:09.378 xcodebuild[34313:1668414] stream error: stream error at offset 29: created by an unsupported XCDependencyGraph build</p>
  
  <p>The following build commands failed:</p>
  
  <p>CompileSwift normal arm64 {Path to swift file}</p>
