对于Xocde 12.0 beta 5:

在底部你会看到字体族。

以下步骤:

去xcode_preferences->然后选择字体和颜色->选择所有的文本选项->点击字体部分，改变你想要的字体

去

Xcode menu > Preferences > Font & Color > Category

双击纯文本，弹出菜单将出现。从这里开始改变。

按“Command”+“+”增加文本大小。 按“Command”+“-”减小文本大小。

在Xcode 13中，你也可以调整

导航器字体大小

在Preferences面板中:

Xcode 13 ->首选项->通用->导航大小

默认情况下，它与系统字体比例匹配，但您可以覆盖设置并选择三个不同的选项之一:“小”，“中”或“大”。

你可以使用以下方法:

出版社xcode - >首选项 选择字体和颜色 选择列表中的任意字体并按cmd+a(选择所有字体) 选择窗口底部所有编辑器字体的字体大小

对于Xcode 4.1

仍然是一个巨大的痛苦。糟糕的UI设计(但我的心态似乎与那些制作100多个字符变量和方法名的软件工程师的心态不一样。我的抱怨够多了)

我将为当前版本修改以前的一篇文章。

Close any projects you have open in Xcode (Otherwise the Font window will be inaccessible while a project is open.) Go to XCode > Preferences > Fonts & Color 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) 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 . . . 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!) In the 'Font' window, click the small, almost hidden, and surely poorly design 'T' icon to the right of the font name and size. Voila! In only 14 keystrokes you are able to get the Font inspector window! 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 Close the windows you opened on this hunt for the holy grail.

祝贺你。你现在可以阅读你的代码了。 这难道不痛苦吗?
