title: How can I use the legacy build system with Xcode 10's `xcodebuild`?
body: <p>I'd like to use the new build system of Xcode 10 for development, but our build in our continuous integration system fails since the <code>xcarchive</code> produced has an issue: the <code>Info.plist</code> in the <code>xcarchive</code> is missing the <code>ApplicationProperties</code> key and the information therein!</p>
  
  <p>It turns out switching back to the legacy build system fixes this. This can be done in the workspace settings (File > Workspace Settings… > Build System). But I would prefer to keep the new build system for development and only use the legacy build system for CI builds.</p>
  
  <p>Is there a way to make <code>xcodebuild</code> use the legacy build system without modifying the workspace?</p>
