title: How do you select the IOS simulator as a target in Instruments?
body: <p>I am new to IOS app development...</p>
  
  <p>How do I select the IOS Simulator as a target from the Instruments application, so I can debug/profile an IOS App running on the simulator.</p>
  
  <p>In Instruments I select:
     File -> New
     then pick the IOS Simulator / Memory / Allocations 'template', click 'choose'</p>
  
  <p>Under 'Choose Target' the only existing targets show are my Macbook and a real iPod device.
  How do I select the IOS Simulator as a target??
  If I select the 'Choose Target' option Instruments brings up a dialog where it wants me to select something from my filesystem... have no idea what to select.</p>
  
  <p>This is Instruments 4.2.</p>
  
  <p>Also, contrary to a various bits of info on the web, I can see no way to launch Instruments from in Xcode 4.2.</p>
  
  <p>Thanks.</p>
