【问题描述】：
我正在尝试在 ios 模拟器上使用 Appium 进行自动化。 我的配置是：
OS version: 10.10.x
Appium: 1.4.0
Xcode: 6.3.2
appium 的上限是：
automationName = "Appium"
platformName = "iOS"
platformVersion = "8.3"
deviceName = "iPhone 5s"
app = "/Users/skaram200/Desktop/ios_build/XfinityMyAccount_6.3.app"
当我运行 appium 时，它给了我一个错误：
info: [debug] Attempting to run app on iPhone 5s (8.3 Simulator)

```
请告诉我，我该如何解决这些错误并开始使用 appium 在 ios 模拟器上实现自动化。
