【问题描述】：

我是 appium 和 eclipse 的新手，我正在尝试在设备上运行简单的脚本。我已经添加了 UDID 并创建了一个配置文件。几天前脚本运行良好，但今天突然间，我 iPad 上的 safari 启动器应用程序也开始崩溃。当我重新安装 safari 启动器并尝试运行脚本时出现下面列出的错误，有没有人遇到过类似的问题？

【解决方案1】：

主要问题始终是 Appium 的不稳定版本。我做了什么，我将 appium 升级到 1.5.3 和 Xcode 8。

然后我去了这个论坛

https://discuss.appium.io/t/bad-app-error-randomly-with-correct-path-and-valid-ipa-file/10191

发现大部分问题都是由appium引起的。

希望它也对其他人有所帮助。
