Appium（和桌面）无法启动 wda 会话，因为 xCode13 和 iOS15
Appium (and desktop) unable to launch wda session since xCode13 and iOS15
由于我的 xCode 已（自动...）更新到 13，并且我所有的模拟器都从 iOS 14.5 移动到 15。使用相同的设置/命令我无法启动来自桌面应用程序和节点的 WDA（硒服务器 grid/node 设置）
所有模拟器都存在该问题。
我还能用真机..
（错误的实际端口可能不同，第一个来自失败的实际自动化，第二个和第三个来自桌面应用程序 - 它仍然失败并出现相同的错误。根本问题仍然存在两者相同)
我得到的错误日志：
简而言之：

为了解决这个问题，
我们需要在电脑上更新我们的appkum（应该是1.22.0或以上）
查看您的版本：
appium -v
要安装/更新您的 appium：
npm install -g appium
这修复了模拟器部分。要修复 appium 桌面，您还必须更新桌面应用程序，但现在它已作为 2 个单独的应用程序移动。
服务器一个
https://github.com/appium/appium-desktop/releases/
还有一个给检查员 https://github.com/appium/appium-inspector/releases
我在旧的 appium（服务器和检查器结合在一起）和新版本中遇到了类似的问题，它们是分开的。
我通过添加服务器功能解决了这个问题：
serverCapabilities.setCapability("wdaStartupRetries", "4");
serverCapabilities.setCapability("iosInstallPause","8000" );
serverCapabilities.setCapability("wdaStartupRetryInterval", "20000");
此后，wda会话稳定
由于我的 xCode 已（自动...）更新到 13，并且我所有的模拟器都从 iOS 14.5 移动到 15。使用相同的设置/命令我无法启动来自桌面应用程序和节点的 WDA（硒服务器 grid/node 设置）
所有模拟器都存在该问题。 我还能用真机..
（错误的实际端口可能不同，第一个来自失败的实际自动化，第二个和第三个来自桌面应用程序 - 它仍然失败并出现相同的错误。根本问题仍然存在两者相同)
