无法通过xcode 7.3.1安装ios 9模拟器
我在OSX（10.11.4 El capitan）Xcode 7.3.1的问题，即当我尝试安装任何模拟器使用sudo /Applications/Xcode.app/Contents/MacOS/Xcode我得到这个错误：
could not download and install ios 9.1 simulator when files are moved to the final location of an unexpected error occured
怎么了？

打开Xcode 。
在菜单栏中，点击Xcode – > Preferences 。
进入“首选项”屏幕后，单击“ 组件”选项卡。
现在，点击所需模拟器旁边的向下箭头 。
您还可以通过检查模拟器保存的目录来检查保存每个模拟器的有效性。
此外，请选中“自动检查并安装更新”checkbox，以避免出现更多此类问题。
