How to highlight all occurrence of the same variable in Xcode?
<p>In Xcode, when I click on a variable's name and wanting to find out the location of the same variable in my code, the Xcode put a very faint line beneath all occurrence, in my case, I tried to find all instance of the "range" variable in my code.</p>

<p>As you can see, the faint line beneath the variable is very hard to spot, so I was just wondering if there is any way that I can make it more obvious?</p>
