There are cases where you may not want to upgrade to the latest version of Xcode.
在某些情况下，您可能不想升级到最新版本的 Xcode。
In my company there are still customers with iPhone 3 that are running iOS 4.2.1 and Xcode 4.5 won't generate code for it. Xcode will generate for 4.3 upwards.
在我的公司中，仍有一些客户使用 iPhone 3 运行 iOS 4.2.1，而 Xcode 4.5 不会为其生成代码。Xcode 将为 4.3 以上生成。
Surprisingly I have an iPhone 3 (A1303) that has been upgraded to iOS 6.0 and Xcode won't generate code for that either.
令人惊讶的是，我有一部已升级到 iOS 6.0 的 iPhone 3 (A1303)，而 Xcode 也不会为此生成代码。
So, for those that do need to downgrade, you use the link that @leo posted to get hold of the dmg for the version of Xcode you want (4.4.1 probably) and mount it. You then find the existing Xcode (in your application folder) and drag it to the waste bin, then drag the downgraded Xcode to the application folder. You may need to re-install the command line tools, if you use them. Make sure you get the version for your Mac's OS.
因此，对于那些确实需要降级的人，您可以使用@leo 发布的链接来获取您想要的 Xcode 版本（可能是 4.4.1）的 dmg 并安装它。然后找到现有的 Xcode（在您的应用程序文件夹中）并将其拖到垃圾箱，然后将降级的 Xcode 拖到应用程序文件夹中。如果您使用命令行工具，您可能需要重新安装它们。确保您获得适用于 Mac 操作系统的版本。
