iOS16.0 线程警告提示

[wangjie172767]

(NSRunLoop *)runLoop; { dispatch_group_wait(_waitGroup, DISPATCH_TIME_FOREVER); return _runLoop; } pod集成， xcode：14.0，iphone14pro，iOS16.0 ，SocketRocket (0.6.0) 警告提示： Thread running at QOS_CLASS_USER_INTERACTIVE waiting on a lower QoS thread running at QOS_CLASS_DEFAULT. Investigate ways to avoid priority inversions

[Daemonson]

The same as #648
