title: Xcode: How do I tell where a warning is coming from?
body: <p>I get the following warning:<code>2015-01-01 12:58:52.793 MyApp[15976:282754] Application tried to represent an active popover presentation:&lt;UIPopoverPresentationController: 0x17dc5940&gt;</code>
  How do I tell which <em>File: Line number</em> is caused the warning?
  I assume that <code>MyApp[15976:282754]</code> is some place in my application.</p>
