更新!看Xcode 9来拯救你! 现在你可以使用cmd +来增加Xcode 9的字体。 你花了5个主要版本才得到它，苹果!但迟到总比不到好。

我算出来了，不过不是很直观。

首先是一些痛点

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? 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!

解决方案是-你需要复制主题，然后修改你刚刚制作的副本，并应用该副本-唷!

对于Xcode 12:(beta 3)

对于代码编辑窗口，请使用new

编辑器->字体大小->增加

or

编辑器->字体大小->减少

菜单项。这将全局地增加或减少所有编辑窗口的字体大小。还有一个

编辑器->字体大小->重置

选择。这些也响应⌘+或⌘-键盘快捷键。

默认情况下，左侧的文件导航器对应于

系统首选项->常规->侧栏图标大小

你也可以在Xcode中使用

Xcode -> Preferences -> General -> Navigator Size

当在XCode中从[Preferences]更改字体时(在复制一个与你想要的颜色匹配的模板后)，你可以选择多个条目并一次更改字体。使用[shift]选择一个范围或[cmd]选择多个单独的条目(例如，您可以同时选择'comments'和'strings'，只更改它们的字体)。

对于Xcode版本12.3及以上(不确定它是否适用于一些旧版本，但你可以尝试一下)

Xcode

-> Preferences -> Themes 
-> Select your favourite theme on left panel 
-> SourceEditor 
-> Select All (`cmd + A`) 
-> Click on T option 
-> Select size

我发现在首选项中，没有字体和颜色选择。我猜版本不一样，下面是最新版本的

方法1

进入Xcode ->首选项 点击主题 点击字体中间的T符号 调整右下角的大小

方法2

只需调整cmd +或cmd -
