ios - 在Xcode 6和Xcode 4.5之间切换

Question

使用OS X Yosemite

按照本指南删除了Xcode6，并安装了Xcode 4.5:
http://iosdevelopertips.com/xcode/install-multiple-versions-of-xcode.html

将Xcode 4.5安装在另一个文件夹下，并使用命令“sudo xcode-select --switch /Applications/Xcode4.5/Xcode.app”(在终端中)切换到新的Xcode4.5版本(来自上述指南)。

收到一条错误消息，指出在首次启动时安装了不兼容的“MobileDevice.Framework”。按照本指南解决该问题:Xcode 4.4.1 does not work properly under OSX Mavericks
从上面的堆栈溢出问题运行命令:“sudo rm -rf /System/Library/PrivateFrameworks/MobileDevice.framework”后，经过数天的研究，我遇到了另一个无法解决的错误:

Answer 1

从10.10开始，似乎没有办法允许工作xcode 4.5和xcode 4.4(尽管OSX 10.9允许解决此问题)

因此，如果要启动它们，则应使用OSX 10.9(Mavericks)。

还有...为什么要使用Xcode 4.5？我不知道有什么理由要使用它。

Xcode 4.4.1-允许在armv6设备上进行调试的最新版本。

Xcode 4.6.3-包含iOS 7设计(SDK 6.1)之前的最新SDK。

但是Xcode 4.5.2的原因是什么？
