How to increment the font size of the Xcode UI?
With Xcode 12 you can also adjust the Navigator font size inside the Preferences panel:
Xcode 12 -&gt; Preferences -&gt; General -&gt; Navigator Size

By default, it matches the system font scale, but you can override the settings and choose one of three different options: &quot;Small&quot;, &quot;Medium&quot; or &quot;Large&quot;.
