我的应用程序运行良好,我没有得到这个错误的Xcode 13.4,是Xcode 14测试版错误或我做了一些坏线程?!
第一个月
我不明白这个问题,所以我也添加了我的堆栈日志:

由于代码中的优先级反转,您将收到此消息。更多详细信息,请单击此处:https://developer.apple.com/documentation/xcode/diagnosing-performance-issues-early
更具体地说,您使用的是
dispatch_group_wait
,它不提供优先级反转避免;所以你的等待线程很容易发生反转,看起来就是这样。8ljdwjyq2#
尝试将您的Xcode更新到14.2。此问题已在更新版本中得到修复。谢谢,
