When changing fonts in XCode from [Preferences] (after duplicating a template that matches colours close to what you want), you can select multiple entries and change the fonts all at once. Use [shift] to select a range or [cmd] to select multiple individual entries (e.g. you might select both 'comments' and 'strings' and change only their fonts).

It is Aug 2011, Xcode 4.1 and it continues to be nightmare. Why not allow Cmd+ and Cmd- like everywhere else.

As suggested by other respondents I suggest that you copy your preferred theme before you tweak the fonts for there is no ease way to undo.

In my case, all I wanted to do was increase the font size. Mercifully you can select multiple items (Shift+select or Cmd+select) and set the font for all the ones selected in one fell swoop.

Minor relief for a major irritation.

For Xcode 12: (beta 3)
For the code editing windows, use the new
<code>Editor -&gt; Font Size -&gt; Increase</code>
or
<code>Editor -&gt; Font Size -&gt; Decrease</code>
menu items. This globally increases or decreases the font sizes for all editing windows. There is also an
<code>Editor -&gt; Font Size -&gt; Reset</code>
option. These also respond to the ⌘+ or ⌘- keyboard shortcuts.
By default, the file navigator on the left side corresponds to the
<code>System Preferences -&gt; General -&gt; Sidebar icon size</code>
You can also override the system size inside Xcode using the
<code>Xcode -&gt; Preferences -&gt; General -&gt; Navigator Size</code>

All previous answers focus on what was possible: change the font size of the editor and debug area. But if you're sharing your screen navigators (File Navigators, etc.) are still tiny. You can change the size now to three presets in <code>Settings &gt; General &gt; Navigator Size</code>.
This will make your files and folders more readable while presenting.
