（总结 wda 编译中出现的问题）
问题一：出现'RoutingHTTPServer/RoutingConnection.h' file not found,编译错误.
问题二：xcodebuild failed with code 65
解决处理方法：
1.cd /Applications/Appium.app/Contents/Resources/app/node_modules/appium-xcuitest-driver/WebDriverAgent
2.在 wda 根目录下,输入 sh ./Scripts/bootstrap.sh 下载依赖，wda 重新编译
3.重新 build 了 project 后，就没有报错了

问题三：当出现以下这个报错，不要着急！！！

解决方法：
就是提示这个 app 尝试安装 但是已经被安装了，
手动卸载模拟机上的已经被安装的 uicatalog,然后重新启动 appium 运行就没有报错了
