Appium 无法在 xCode 13.3 和 iOS 15.4 上截屏
Appium unable to take screenshot on xCode 13.3 and iOS 15.4
我几天前醒来 运行 在 iOS 模拟器上进行了 appium UI 自动化测试，运行 完美无误地进行了测试。我最近升级到 iOS 15.4 和 iOS 13.3，令我惊讶的是 Appium 无法再次截屏。我试着检查可能是什么原因，并在此处 Socket hang up error while taking screenshot in appium (iOS 15.4 beta & xCode 13.3 beta 2). I find this as well on Apple post Xcode 12 Beta 3 Release Notes 发现了完全相似的问题。目前有任何解决方法吗？

改回iOS 15.2我遇到了同样的问题，苦苦挣扎了好几个小时……什么都试过了……和你的情况完全一样。昨天它在工作，今天突然停止工作。所以最后，唯一的变化是 xcode 模拟器从 15.2 更新到 iOS 15.4。这就是为什么 appium inspector 停止工作并截取屏幕截图的原因。我想从 appium 方面更新需要一些时间，但在那之前只需回到最新的稳定 iOS 模拟器版本 15.2。 如何操作 - Xcode -> 首选项 -> 组件 -> select 旧 iOS 版本模拟器 -> 下载，立即检查并安装 -> 构建 -> 瞧:)
可以通过更改WebDriverAgentLib/Utilities/FBScreenshot.m（第257行）来修复：
(nullable id)screenshotRequestWithScreenID:(unsigned int)screenID
至：
(nullable id)screenshotRequestWithScreenID:(long long)screenID
