Just an extension to this. I'm using OSX Lion and you can install/update via the App Store.
只是对此的扩展。我正在使用 OSX Lion，您可以通过 App Store 安装/更新。

To update Xcode, sadly, you have to download the entire .dmg file from Apple's website again.
遗憾的是，要更新 Xcode，您必须再次从 Apple 的网站下载整个 .dmg 文件。

I recommend installing into a different folder in the root of your hard drive. I have had problems in the past, not with this specific upgrade, that were fixed by doing a fresh install.
我建议安装到硬盘驱动器根目录中的不同文件夹中。过去我遇到过问题，不是这次特定的升级，而是通过全新安装解决的。

In my case, when I cannot see it in the AppStore Update section I searched for it in the AppStore and once I saw Xcode in the search results it displays a button below it saying "Update" if you are not in the latest version.
就我而言，当我在 AppStore 更新部分看不到它时，我在 AppStore 中搜索了它，一旦我在搜索结果中看到 Xcode，它就会在它下方显示一个按钮，如果您不是最新版本，则显示“更新”。

I upgraded from 10.7.5 to 10.11.5 on my pro and it rendered my old Xcode (4.4.1) unusable on the new OS. I had to download a new version from App Store. I guess the update feature is not enabled yet in Xcode 4 (as @Dominic mentioned)
我在专业版上从 10.7.5 升级到 10.11.5，这导致我的旧 Xcode (4.4.1) 在新操作系统上无法使用。我不得不从 App Store 下载一个新版本。我猜更新功能尚未在 Xcode 4 中启用（如@Dominic 所述）
