【问题讨论】：

错误说设备不可用。尝试强制关闭模拟器，关闭appium并再次运行。
完成但问题仍然存在.. 错误：找不到要启动的设备。您要求“iPhone（9.0 模拟器）”我实际上在 appium 设备设置中设置了“iPhone 6”操作系统：9.0 但是 appium 给了我上述错误
好像 Appium 1.4.8 不支持 iOS9。我已将 Xcode 7 降级为安装了 iOS8.4 的 Xcode6.4。模拟器正在成功启动 iOS 应用程序。
我通过将appium升级到1.4.13成功启动了测试，但是从那时起appium在屏幕上找不到任何元素（NoSuchElementException）所以我现在下载iOS8.4模拟器尝试

【解决方案1】：

因为Appium1.4.13 不处理xcode7。你请求了iPhone (9.0 Simulator)，但iPhone 6 (9.0) [1F54D699-8136-4F4D-8E34-16B6CCA808E4] 可用。您应该在以下位置修改ios.js：

/Applications/Appium.app/Contents/Resources/node_modules/appium/lib/devices/ios 这是我修改的方式。

else if (opts.xcodeVersion[0] === '5') {
    iosDeviceString += isRetina ? " Retina" : "";
    if (isiPhone) {
      if (isRetina && isTall) {
        iosDeviceString += is64bit ? " (4-inch 64-bit)" : " (4-inch)";
      } else if (deviceName.toLowerCase().indexOf("3.5") !== -1) {
        iosDeviceString += " (3.5-inch)";
      }
    } else {
      iosDeviceString += is64bit ? " (64-bit)" : "";
    }
  } 

  else if (opts.xcodeVersion[0] === '6') {
    iosDeviceString = opts.deviceName ||
      (isiPhone ? "iPhone Simulator" : "iPad Simulator");
  }

  else if (opts.xcodeVersion[0] === '7') {
    iosDeviceString = opts.deviceName ||
      (isiPhone ? "iPhone Simulator" : "iPad Simulator");
  }




  var reqVersion = opts.platformVersion || opts.iOSSDKVersion;
  if (9>opts.iOSSDKVersion >= 8) {
    iosDeviceString += " (" + reqVersion + " Simulator)";
  } 
  else if (8>opts.iOSSDKVersion >= 7.1) {
    iosDeviceString += " - Simulator - iOS " + reqVersion;
  }
  else if(opts.iOSSDKVersion>=9){
    iosDeviceString += " (" + reqVersion+ ")";
  }
