无法启动iOS模拟器Xcode 7

[英]unable to boot iOS simulator Xcode 7

I know this is repetitive question,but i tried all ways but it is not working. 我知道这是重复性的问题,但是我尝试了所有方法,但是没有用。 I have XCode 7 and XCode 7.2 on my machine and whenever I run the code it shows "Unable to boot iOS simulator". 我的机器上装有XCode 7和XCode 7.2,每当我运行代码时,它就会显示“无法启动iOS模拟器”。

I also tried to uninstall Xcode by using below command, 我还尝试使用以下命令卸载Xcode,

sudo /Developer/Library/uninstall-devtools --mode=all 须藤/ Developer / Library / uninstall-devtools --mode = all

But I am getting error "command not found". 但是我收到错误消息“找不到命令”。 When I run "which sudo" it shows me below path -> "/usr/bin/sudo" 当我运行“ which sudo”时,它显示在路径->“ / usr / bin / sudo”下

Am I missing anything? 我有什么想念的吗?

I tried a lot but didn't succeed. 我尝试了很多,但没有成功。 Meanwhile I upgraded my Mac OS version to EI Captain and It worked. 同时,我将Mac OS版本升级为EI Captain,并且可以正常工作。 I know this is not answer to my question but this one solved my problem. 我知道这不是我的问题的答案,但是这个解决了我的问题。
