How to profile React Native source code using Xcode/Instruments/Time Profiler : <p>We're using React Native <code>0.59.10</code> and React-Redux <code>5.0.7</code>, and are experiencing a CPU-bound performance issue, in which our Redux actions are taking ~0.25s to complete.</p>

<p>We've profiled using the Time Profiler configuration in Instruments, but none of our JS code is symbolicated.</p>

<p>Remotely debugging in Chrome seems to just debug the "remote inspector" page, which is entirely unhelpful.</p>

<p>Is there a way to build/attach a source map, or symbolicate the memory addresses seen below, to the JS function names/calls?</p>
