Why is a closing brace showing no code coverage?
<p>I've got a Swift function for which Xcode is showing 0 passes in code coverage. The line is a closing brace (highlighted in red below).</p>

<p>Is this a bug in Xcode? If not, what condition do I need to hit to run that line? I thought I was covering all paths through this method.</p>
