Xcode 6 和 Xcode 5 可以在同一台电脑上共存吗？

Can Xcode 6 and Xcode 5 coexist on the same computer?

提问by mredig

I currently have and use Xcode 5, and while I'd like to experiment with Xcode 6, I don't want to use it for production. Can I have both of them installed on the same computer without them conflicting with each other? I couldn't find anything on this on the download page for Xcode 6.

我目前拥有并使用 Xcode 5，虽然我想尝试使用 Xcode 6，但我不想将它用于生产。我可以将它们安装在同一台计算机上而不相互冲突吗？我在 Xcode 6 的下载页面上找不到任何关于此的内容。

I have them installed side by side right now and I have not encountered any problems with this arrangement. While I obviously haven't had Xcode 6 for very long, I have done the same thing with several previous Xcode beta releases as well and I have no reason to believe this release would be different.

我现在并排安装了它们，并且我没有遇到这种安排的任何问题。虽然我显然没有很长时间使用 Xcode 6，但我对之前的几个 Xcode 测试版也做了同样的事情，我没有理由相信这个版本会有所不同。

EDIT: You can use xcode-selectto switch between the different versions of the command line tools. From the man page:

编辑：您可以用来xcode-select在不同版本的命令行工具之间切换。从手册页：

When multiple Xcode applications are installed on a system (e.g. /Applications/Xcode.app, containing the latest Xcode, and /Applications/Xcode-DP.app containing a developer preview) use xcode-select --switch path/to/Xcode.app to specify the Xcode that you wish to use for command line developer tools.

当系统上安装了多个 Xcode 应用程序（例如，包含最新 Xcode 的 /Applications/Xcode.app 和包含开发人员预览的 /Applications/Xcode-DP.app）时，请使用 xcode-select --switch path/to/Xcode。 app 来指定您希望用于命令行开发人员工具的 Xcode。

As said before - XCode 5 and 6 can coexist together. Just want to add that you can switch between the different versions of the command line tools using the GUI also: open XCode-> Preferences-> Locations.

如前所述 - XCode 5 和 6 可以共存。只想补充一点，您还可以使用 GUI 在不同版本的命令行工具之间切换：打开XCode-> Preferences-> Locations。

They can both coexist without any problems. You can set version that command line tools use with:

它们可以共存，没有任何问题。您可以设置命令行工具使用的版本：

sudo xcode-select -s /Applications/Xcode6-Beta.app

Xcode 6 works on 10.9 too.

Xcode 6 也适用于 10.9。

My Xcode 5 icon in the dock turned into a big question mark, as it appears to have been deleted with the install of Yosemite. Further, If I try to re-download it from the app store, it says my version of OS X is 'too new' and refuses to allow me to download. Next I downloaded Xcode 5.1.1 from the developer downloads, which finally allowed me to install it. They are both happily coexisting now on Yosemite.

我在 Dock 中的 Xcode 5 图标变成了一个大问号，因为它似乎已随着 Yosemite 的安装而被删除。此外，如果我尝试从应用商店重新下载它，它会说我的 OS X 版本“太新”并且拒绝让我下载。接下来，我从开发人员下载中下载了 Xcode 5.1.1，这最终允许我安装它。他们现在在优胜美地愉快地共存。

Yes, you can have two Xcode on system but it is advised to keep latest one. While installing Xcode 6 there will be prompt 'Xcode already exists. Replace/Keep it ?'

是的，您可以在系统上安装两个 Xcode，但建议保留最新的一个。在安装 Xcode 6 时，会提示“Xcode 已经存在。更换/保留它？'

Go with create a new copy of Xcode.This will install Xcode 6 on your system. The newly installed Xcode will be renamed as 'Xcode 6'. I'm using Xcode 5.1 and Xcode 6 on my system and there seems to be no issue.

去创建一个新的 Xcode 副本。这将在您的系统上安装 Xcode 6。新安装的 Xcode 将被重命名为'Xcode 6'。我在我的系统上使用 Xcode 5.1 和 Xcode 6，似乎没有问题。

yes you can have two separate version on same mac

是的，您可以在同一台 Mac 上拥有两个单独的版本

1. Xcode 6 on the Mac App Store will replace the existing Xcode installation. Only the Xcode betas install separately (by default)

2. Only downloading Xcode from https://developer.apple.com/downloads/and doing the install manually (by copying Xcode from the DMG to /Applications) will prompt you to replace or keep both.

1. Mac App Store 上的 Xcode 6 将替换现有的 Xcode 安装。仅 Xcode beta 单独安装（默认情况下）

2. 只有从https://developer.apple.com/downloads/下载 Xcode并手动安装（通过将 Xcode 从 DMG 复制到 /Applications）才会提示您替换或保留两者。

Select the keep both option when prompt.

出现提示时选择保留两个选项。
