How can I increase the font size in Xcode version 3.2.3
When I go to Edit -> Format -> Fonts -> Show Fonts and try to increase the font size, nothing happens.
top menu bar: XCODE - PREFERENCES - FONTS AND COLORS
choose a style NOT default (i took 'basic')
select one, like PLAIN TEXT, click on the font box, next to the font and size description, a popup will appear - keep that open
go back to the SOURCE EDITOR tab in FONTS AND COLORS
select all of the options, from PLAIN TEXT DOWN
go back to the popup window, choose your preferred font and size, DOUBLE CLICK ON THE FONT SIZE - all of them will change at once. or you can do them one by one, your choice.
You need to go to Xcode > Prefrences > Font and Color and change the font there.

How to increase font size in the Xcode editor?
1.Close any projects you have open in Xcode (Otherwise the Font window will be inaccessible while a project is open.)
2.Go to XCode > Preferences > Fonts & Color
3.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)
4.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 . . .
5.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!)
6.In the 'Font' window, click the small, almost hidden, and surely poorly design 'T' icon to the right of the font name and size.
7.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 > 16
