For people having the "Unable to boot the iOS Simulator" issue while running Xcode 6.x under OS X 10.11 El Capitan, be warned that there is no effective solution as the iOS 7 simulator is functionally incompatible with El Cap.
对于在 OS X 10.11 El Capitan 下运行 Xcode 6.x 时遇到“无法启动 iOS 模拟器”问题的人，请注意没有有效的解决方案，因为 iOS 7 模拟器在功能上与 El Cap 不兼容。

"This is a specific incompatibility of the iOS 7.1 libxpc being too old to satisfy the needs of the host's libsystem_stats.dylib."
“这是 iOS 7.1 libxpc 太旧而无法满足主机的 libsystem_stats.dylib 需求的特定不兼容性。”
Posting this because I spent hours pounding my head into the wall trying to "fix" an unfixable problem.
发布这个是因为我花了几个小时把头撞到墙上试图“解决”一个无法解决的问题。

The "Unable to boot the iOS Simulator" error message usually appears as a result of CoreSimulator failing to kick off launchd_sim to boot the simulated device.
“无法启动 iOS 模拟器”错误消息通常是由于 CoreSimulator 无法启动 launchd_sim 来启动模拟设备而出现的。
In your case, the issue is that launchd_sim is crashing on launch because it can't bind to the syslog socket, which is located at /private/tmp/com.apple.CoreSimulator.SimDevice.[DEVICE UDID].launchd_sim/syslogso
在您的情况下，问题是 launchd_sim 在启动时崩溃，因为它无法绑定到位于 /private/tmp/com.apple.CoreSimulator.SimDevice.[DEVICE UDID].launchd_sim/syslogso 的 syslog 套接字
Try deleting /private/tmp/com.apple.CoreSimulator.SimDevice.*:
尝试删除 /private/tmp/com.apple.CoreSimulator.SimDevice.*：
sudo rm -rf /private/tmp/com.apple.CoreSimulator.SimDevice.*
