Xcode安装之后，simctl可以通过xcrun命令来执行。
你可以通过直接输入xcrun simctl来查看它支持的作用。

usage: simctl [--set <path>] [--profiles <path>] <subcommand> ...
       simctl help [subcommand]

Command line utility to control the Simulator。
通过这个命令可以方便地控制模拟器。

管理设备xcrun simctl list

通过运行xcrun simctl list可以获取到当前可用的设备列表，包括设备类型、设备系统版本、设备名称、设备UUID，运行状态等信息。
每个设备都有一个独一无二的UUID，这个是其他simctl子命令需要的参数

For subcommands that require a <device> argument, you may specify a device UDID
or the special "booted" string which will cause simctl to pick a booted device.
If multiple devices are booted when the "booted" device is selected, simctl
will choose one of them.

因为部分子命令需要 设备参数，你可以通过指定设备的UUID或booted让命令自行选中一个已经启动的设备。如果多个模拟器已经启动，simctl将选择其中的一个。

启动模拟器 xcrun simctl boot $UUID

用来启动模拟器，其中的UUID参数就是之前列表中的UUID。
既然有启动模拟器，自然也就有关闭模拟器xcrun simctl shutdown $UUID、重置模拟器xcrun simctl erase $UUID

清理不可用的模拟器 xcrun simctl delete unavailable

当Mac空间不够用时，这条命令或许可以帮你重获不是磁盘空间。

在模拟器与Mac设备之间进行复制&粘贴pbcopy & pbpaste

• pbcopy 复制内容到Mac设备的剪贴板
• pbpaste 将 Mac设备的剪贴板的内容进行粘贴
• xcrun simctl pbcopy booted 将Mac设备中剪贴板上的内容复制到模拟器上的剪贴板上 【方向：Mac=》模拟器】
• xcrun simctl pbpaste booted 将模拟器中剪贴板上的内容复制到Mac设备上的剪贴板上 【方向：模拟器=》Mac】
• xcrun simctl pbsync sourceDevice destDevice 将source设备中剪贴板上的内容同步到dest设备上的剪贴板上 【方向：source《=》dest】,其中可以用 host 表示Mac设备

模拟器截屏 xcrun simctl io booted screenshot app-screenshot.png

模拟器录屏 xcrun simctl io booted recordVideo app-preview.mp4

执行命令后，录制完成时"Ctrl + C"结束，这个时候到指定位置找响应的视频文件即可

设置模拟器位置

指定UUID的数据目录~/Library/Developer/CoreSimulator/Devices/,
模拟器偏好文件位于data/Library/Preferences/.GlobalPreferences.plist，里面包含许多设置，
可以通过plutil命令来查看，具体如下：

plutil -p ~/Library/Developer/CoreSimulator/Devices/$UUID/data/Library/Preferences/.GlobalPreferences.plist

同样，修改也是通过plutil来实现，示例如下：

PLIST=~/Library/Developer/CoreSimulator/Devices/$UUID/data/Library/Preferences/.GlobalPreferences.plist

LANGUAGE="ja"
LOCALE="ja_JP"

plutil -replace AppleLocale -string $LOCALE $PLIST
plutil -replace AppleLanguages -json "[ \"$LANGUAGE\" ]" $PLIST

更多功能可以通过plutil -h来查看
