Error Running React Native App From Terminal (iOS)
<p>I am following the tutorial on the official React Native website.</p>

<p>Using the following to build my project:</p>

<pre><code>react-native run-ios
</code></pre>

<p>I get the error:</p>

<pre><code>Found Xcode project TestProject.xcodeproj
xcrun: error: unable to find utility "instruments", not a developer   
tool or in PATH

Command failed: xcrun instruments -s
xcrun: error: unable to find utility "instruments", not a developer 
tool or in PATH
</code></pre>

<p>Although, when I run the app from the .xcodeproj, everything works fine.</p>

<p>Any suggestions?</p>
