title: Set the default scheme for Xcode project
body: <p>I have an Xcode project MyApp (with 1 target MyApp), that includes another project LibProject (with 2 targets, lib and app).  I have autocreate schemes selected in the Xcode ui, and when I first open the project it does indeed create the schemes but one of the schemes from the nested LibProject is selected whereas I want the single target/scheme from MyApp to be selected.  I can change the scheme after the fact and the UI remembers, but I don't want to have Xcode default to an incorrect scheme. </p>
  
  <p>The order the schemes end up:</p>
  
  <pre><code>lib (*with this one selected)
  app
  MyApp  
  </code></pre>
  
  <p>Any idea how to select the default for newly created schemes?</p>
