Breakpoints not hit in Xcode (9.3) : <p>None of my breakpoints are being hit.</p>

<p>I've tried the following:</p>

<ul>
<li>Deleted Derived Data directory</li>
<li>Cleaned build folder</li>
<li>Deleted the xcuserdata directory</li>
<li>Made sure build configuration is <code>Debug</code> and <code>Debug executable</code> is
ticked</li>
<li>Made sure   <code>Generate debug symbols</code> is set to <code>Yes</code></li>
<li>Changed <code>Optimization level</code> to <code>No optimization</code></li>
</ul>

<p>The breakpoints are still not being hit.</p>
