首先说明：使用 iOS 模拟器可以正常使用 appium-desktop，但是使用真机就起不来啊：
wda 是安装的 appium1.6.4 的那个，appium1.6.4 可以正常跑通，但是运行 appium-desktop 的时候他会自动把真机上的这个 wda 删除，我想问有没有 appium 专用的 wda 呢？
先看我的参数设置啊：

以下是 appium-desktop 的报错信息：请看这句：[XCUITest] Error: Unable to launch WebDriverAgent because of xcodebuild failure: xcodebuild failed with code 65
