xcrun 是 xcode 提供的 ios模拟器

在![Mac M1 平台搭建 appium 环境](/2021/11/30/using-appium-in-m1.html) 我们讲解xcode的安装，他默认就会安装模拟器

1. 查看已安装的模拟器（其中Boot状态的为启动状态）
xcrun simctl list

iPhone 8 (29088676-5082-4F66-B5B8-94A5397F32F3) (Booted)
iPhone 11 (B77636AB-B849-4672-8D9D-9DBC0E9DC452) (Shutdown)

29088676-5082-4F66-B5B8-94A5397F32F3 则是他的uuid

2. 开启指定的模拟器(open -a Simulator 打开模拟器页面)
xcrun simctl boot udid

3. 关掉模拟器
xcrun simctl shutdown udid

4. 重置模拟器(清除模拟器的数据和设置)
xcrun simctl erase udid

5. 安装指定app
xcrun simctl install booted <app路径>

6. 运行指定的app
xcrun simctl launch booted <bundle identifier>

多设备下，可以将boot关键字修改为 uuid，这样可以指定安装
xcrun simctl launch uuid <bundle identifier>

7. 关闭已经打开的应用
xcrun simctl terminate booted <bundle identifer>

8. 卸载指定应用
xcrun simctl uninstall booted <bundle identifer>

9. 截图

10. 录屏
