我在OSX 10.9.5上将Xcore从v5.1更新到v6.1.1，现在iOS模拟器无法启动。它报告错误'无法启动设备。
我找到了其他帖子，例如IOS 8 Simulator unable to boot和Unable to boot the iOS Simulator - xcode 6.0.1，但这些帖子中的解决方案不起作用。
我试过了：
以上所有解决方案都没有解决问题。启动ios模拟器时有一些崩溃日志。

此问题的最常见原因是DYLD_INSERT_LIBRARIES设置为OS X库。
我建议您取消设置DYLD_INSERT_LIBRARIES（可能在/etc/launchd.conf中）或以其他方式卸载设置它的产品，然后重新启动。
OS X Yosemite有一个软件更改来处理这种情况，所以如果您需要设置DYLD_INSERT_LIBRARIES的产品，我建议您更新到OS X Yosemite进行开发。
但是，既然您已提供崩溃日志，我可以告诉您该问题可能是您系统上的问题。 launchd_sim正在中止，因为它无法在/ private / tmp中创建一个目录。我怀疑你已经修改了/ private / tmp的权限，这样就失败了：
mkdir /private/tmp/com.apple.CoreSimulator.SimDevice.FE1168B2-EE8D-4C69-8AE7-99F5A80F808B.launchd_sim
您应该修复/ private / tmp的权限，并防止它们在将来搞砸。由于这个原因，除了iOS模拟器之外还有很多其他的东西会破坏。
答案 1 :(得分：1)
iOS 8.3，XCode 6.3 我在以下地方观察过类似的调用堆栈： 〜/库/日志/ DiagnosticReports / launchd_sim_＆LT;邮戳＆GT; _＆LT; yourHostName＆GT; .crash
我要强调Jeremy Huddleston Sequoia所说的权限在某些情况下应该归咎于权限。 （如我的）
修复：
sudo diskutil repairPermissions /
- 修复系统目录的权限（如果/ tmp不正确）。
如果我没有设置DYLD_INSERT_LIBRARIES变量，这对我有用。 （即“echo $ DYLD_INSERT_LIBRARIES”返回空白）。我真的在敲打这个。我已经卸载了Xcode /重新启动/删除模拟器/等，如多个不同的S.O.讯息。
根本原因：
问题源于另一个应用程序，该应用程序抱怨没有对/ tmp文件夹的写访问权限，因此我更改了权限而不知道我的操作的全部后果。运行上面的diskutil命令修复了它和它找到的更多文件夹没有设置它们应该是。
现在我的模拟器运行了，我可以在Xcode中继续我的UI调试。
很棒的回答杰里米！谢谢!!
答案 2 :(得分：0)
我做了一个sudo chown $user:wheel /private/tmp而它似乎已经为我解决了。
