Xcode都升级好了，但是appiumdesktop没有重启

An unknown server-side error occurred while processing the command. Original error: Unable to launch WebDriverAgent because of xcodebuild failure: "xcodebuild failed with code 65". Make sure you follow the tutorial at https://github.com/appium/appium-xcuitest-driver/blob/master/docs/real-device-config.md.

这种情况是用appium-desktop工具可以起来应用，但是用脚本跑的话跑不起来，会报这个错误    
需要配置并编译appium-desktop本身的WebDriverAgent，appium-desktop本身的WebDriverAgent路径在：    
    /Applications/Appium.app/Contents/Resources/app/node_modules/appium-xcuitest-driver/WebDriverAgent
