自从我开始使用Xcode 8进行iOS 10开发以来，我的控制台充斥着我没有激活的各种日志。在Xcode 7.3.x中它们没有出现：
[] nw_endpoint_handler_cancel [22.2 23.23.94.109:443 initial path (null)]
[] nw_endpoint_handler_cancel [22.3 23.23.98.165:443 initial path (null)]
[] nw_endpoint_handler_cancel [22.4 23.23.161.173:443 initial path (null)]
[] nw_endpoint_handler_cancel [22.5 50.17.182.35:443 initial path (null)]
[] nw_endpoint_handler_cancel [22.6 50.17.185.176:443 initial path (null)]
[] nw_endpoint_handler_cancel [22.7 50.17.217.30:443 initial path (null)]
[] nw_endpoint_handler_cancel [22.8 23.23.77.27:443 initial path (null)]
[] nw_resolver_cancel_on_queue 0x610000111700
[] -[NWConcrete_tcp_connection dealloc] 22
如何关闭它们？或者有人知道哪个库可能导致它们吗？
