运行命令

./gidevice xctest com.facebook.WebDriverAgentRunner.xctrunner -u xxxx --env=USE_PORT=8100 --env=MJPEG_SERVER_PORT=9100

执行一段时间后，运行基于 appium 的 UI 自动化脚本时，出现如下报错然后自动退出：

 t =  3505.76s     Requesting snapshot of accessibility hierarchy for app with pid 566
    t =  3506.16s     Find: Descendants matching type Any
    t =  3506.17s     Find: Elements matching predicate '(wdType == "XCUIElementTypeTextField" AND wdValue == "请输入手机号") AND (1 == 1 OR identifier == 0 OR frame == 0 OR value == 0 OR title == 0 OR label == 0 OR elementType == 0 OR enabled == 0 OR placeholderValue == 0 OR selected == 0)'

目前为偶现，暂时未找到稳定复现步骤。

偶现这个问题时，是否都恰好在 app 元素较多的页面？

有没有试过调整ios获取控件层数约束一下

查看了一下当时的日志，出现这个问题时，手机是在登录页面。完整控件树如下：

不知道这个算不算多，但目前并不是必现的，大部分情况下在这个界面是可以正常输入手机号什么的。不过没太理解，这个 panic 是因为控件多引起的吗？

不是这原因，只是因为看提供的日志，恰好停留在匹配元素的输出后面，

结合报错信息，猜测可能是响应过大，同时赶上未知的原因导致接收的数据不完整，

所以只是猜测，问这个只是为了判断是否可能存在这种可能。

原因暂无思路定位，但这个 panic 可以避免掉，

晚些时候我做一些调整，这种情况数据不完整的情况可能还是会出现

这个不好约束，毕竟项目控件深度这个目前没有严格规范限制。我现在用的是 wda 的默认值（印象中是50）。而且这个问题并不是必现，一样的脚本这个问题只是偶现，所以因为这个问题调整 wda 的控件深度，有点不大合适。

⚠️只是现状无法定位的猜测

已尝试避免 panic v0.5.2，有空再试一试
