Update! - Behold Xcode 9 to the rescue!
Now you can use cmd + to increase the fonts with Xcode 9.
It took 5 Major releases for you to get it, Apple! But better late than never.

figured it out - however it was not very intuitive.

First some Pain Points

<ol>
<li>When You try to change the font size directly using edit -> format -> font, nothing happens! - Not a good UX ... moreover why play dumb when you can tell user that they are using default or "System-owned" theme and they cannot change it? - Bad Design and more bad UX ... Why keep this option (Cmd t) alive, which by the way is most standard way to increase font size across most well behaved mac apps, if you do not want user to change the font this way?</li>
<li>In Xcode preferences, when you try to change the font size by clicking on "fonts and colors", thats when XCode gives a pop-up saying what needs to be done. Also making a duplicate and then changing the fonts and colors is a lot of work rather than giving a button that says "Restore to Defaults" if Apple is so worried about the user messing up the default settings!</li>
</ol>

The solution is that - you need to duplicate the theme and then modify the copy you just made and apply that copy - phew!

blocks|key|1378243|text|从Preferences更改XCode中的字体时，可以选择多个条目并一次更改所有字体。使用shift键选择一个范围，或使用cmd键选择多个单独的条目(例如，您可以同时选择“注释”和“字符串”，并且只更改它们的字体)。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1378244|史蒂夫|1378245|entityMap|0|LINK|mutability|MUTABLE|url|after+duplicating+a+template+that+matches+colours+close+to+what+you+want^0|1|B|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

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.
&lt; end rant >

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 4.1

Still a huge pain. Poor UI design (But my mindset does not seem to match the mindset of software engineers that make 100+ character variable and method names. Enough of my complaining)

I'll modify a previous post for the current version.

<ol>
<li>Close any projects you have open in Xcode (Otherwise the Font window will be inaccessible while a project is open.)</li>
<li>Go to XCode > Preferences > Fonts &amp; Color</li>
<li>From the 'Theme' box select the theme you want to modify (or select the theme you want to modify and click the "+" button at the bottom of the theme list to clone it first for backup, for there is no undo option)</li>
<li>In the source editor box there is a list of types of text that you may set the font for:
 Plain text
 Comments
 Documentation Comments
 .
 .
 .</li>
<li>Select any or all items from the source editor list and the name and size of the font for
that particular text will show up in the 'Font' window below the 'Source Editor' window.
(If you happen to skip highlighting one of these, you will be able to get to the Font
Inspector and select new sizes, but will wonder why the changes you make are not being
applied!)</li>
<li>In the 'Font' window, click the small, almost hidden, and surely poorly design 'T' icon 
to the right of the font name and size.</li>
<li>Voila! In only 14 keystrokes you are able to get the Font inspector window!</li>
<li>Your existing font will be preselected in the font inspector. Whatever changes you make now
will be applied to the text types you selected in the 'Source Editor' window.
e.g. All Fonts > Menlo > Regular > 14</li>
<li>Close the windows you opened on this hunt for the holy grail. </li>
</ol>

Congratulations. Your may now read your code.
Wasn't that painless?

I also found that you can change the fonts for printing which is controlled by the "Printing" theme. I wanted the print output to be the same as the default, but with a larger font.

<ol>
<li>rename "printing" to "printing1" (select the printing theme and click on it and it should allow you to change the name).</li>
<li>click the "+" and select "Default" from the "New Theme From Template" selection</li>
<li>rename it "Printing"</li>
<li>click in the font area for "Source Editor" and cmd-A to select all of the fonts</li>
<li>change the font size to some desired value (I like 12 point) by clicking the "T" icon and selecting the desired font size</li>
</ol>

After this the printouts should match the new "Printing" template (i.e. in color and bigger, or however you make the template), the key is that printing takes its formating from the "Printing" Theme.

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>

I found that in the <code>Preferences</code>, there is no <code>fonts and colors</code> selection. Guess the version is different, following is the one that works for the latest version.

<li>Click <code>Themes</code></li>
<li>Click the <code>T</code> symbol in the middle of the font</li>

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.

It is as simple as that. Apart from that you can specify text size /font/color for each category in Xcode Preferences -&gt; Themes.

With Xcode 13 you can also adjust the
<blockquote>
Navigator font size
</blockquote>
inside the Preferences panel:
<blockquote>
Xcode 13 -&gt; Preferences -&gt; General -&gt; Navigator Size
</blockquote>
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;.
