提问by inexcii
For Mac / iOS developers, there is a period that we have to use Xcode beta version so as to build a test environment for the new/pre-released version of OS X / iOS. So my question is:
对于 Mac / iOS 开发者来说，有一段时间我们不得不使用 Xcode beta 版本，以便为 OS X / iOS 的新/预发布版本构建测试环境。所以我的问题是：
What is the standard process of updating Xcode beta version, for example, from beta 1 to beta 2?
Xcode beta 版本更新的标准流程是什么，例如从 beta 1 到 beta 2？
Is it necessary to remove beta 1 completely and then install a newly downloaded beta 2?
是否有必要完全删除 beta 1，然后安装新下载的 beta 2？
Is there any shortcut to achieve this process?
有什么捷径可以实现这个过程吗？

Since Beta releases are generally released to developers with Apple Developer Account, a standard process of updating:
由于 Beta 版本通常会发布给拥有 Apple Developer Account 的开发者，因此标准的更新流程：
- Login to Apple Developer Account
- Go to iOS Dev / Mac Dev / Safari Dev Beta content
- Follow links to download and install Beta releases
- 登录苹果开发者账号
- 转至 iOS Dev / Mac Dev / Safari Dev Beta 内容
- 按照链接下载和安装 Beta 版本
Multiple versions of Xcode can be Maintained. E.g I have Xcode Beta 1 installed in /Applications/Xcode 6/Beta 1/and Beta 2 installed in /Applications/Xcode 6/Beta 2/. As of speaking now, Xcode 6 Beta 3 is released, you can install that on /Applications/Xcode 6/Beta 3/. Here is linkto get started.
可以维护多个版本的 Xcode。例如，我安装了 Xcode Beta 1，安装了/Applications/Xcode 6/Beta 1/Beta 2 /Applications/Xcode 6/Beta 2/。截至目前，Xcode 6 Beta 3 已发布，您可以将其安装在/Applications/Xcode 6/Beta 3/. 这是开始的链接。
Also note that to setup app testing environment with Beta releases, there is good reference here.
另请注意，要使用 Beta 版本设置应用程序测试环境，这里有很好的参考。
Beta releases are not on iTunes so we can't take advantage of one click update.
Beta 版本不在 iTunes 上，因此我们无法利用一键更新。
