  <p>The 1ˢᵗ question (supposedly) has an answer, but I can't figure out <strong>how <em>exactly</em> should you use the <code>Aggregate</code> target</strong> (if this is the right direction at all), and apparently neither could Josh Kahane, the OP; the "answer" still somehow got/remained accepted.</p>
  
  <p>The 2ⁿᵈ question was closed down as a "duplicate", as if the 1ˢᵗ one provided a (workable) answer.</p>

  <p>Added a bounty: (how) can one use <code>Aggregate</code> target for simultaneous, multiple <code>Build &amp; Run</code>? Perhaps one can achieve simultaneous, multiple <code>Build &amp; Run</code> via some <code>.sh</code> script using <code>xcodebuild</code>? Any other possible solution?</p>
