在创建构建之后,我遇到了一个错误,我认为这个错误导致一些数据无法获取.
我不知道从哪里开始,但它似乎与http调用有关.无论哪种方式,我不喜欢这些错误的外观,需要深入了解事物.

这些错误意味着什么,我怎么去找哪个地方?
这些错误报告是否与iOS 9中NSURLConnection的折旧有关?
我刚刚更新到Xcode 8/iOS 10 SDK,现在当我编译并运行我的应用程序时,我[DYMTLInitPlatform] platform initialization successful在输出中的所有其他日志之前得到了.
这不是有害的或任何东西,但我想知道该消息是什么,与Xcode 7.3/iOS 9.3 SDK不相关.

知道是什么导致了这个吗?
最近更新到iOS 12.1(从12.0开始)和Xcode 10.1(从10.0开始),并且在我的物理设备上进行调试时,在Xcode控制台中看到大量错误消息,如下所示:
[NetworkInfo] Signal strength query returned error: Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied", descriptor: <CTServiceDescriptor 0x28051d700, domain=1, instance=1>
我每隔几秒钟就会收到几个这样的日志,唯一改变的是CTServiceDescriptor的十六进制值。没有代码更改,因此我必须假定其与iOS或Xcode更新有关。
据我所知,它似乎并未对性能产生任何影响,该应用程序正在按预期运行,并且我的手机正在运行(甚至可以更新其信号强度!)。我在Stack Overflow,Google或Apple Developer论坛上找不到任何有用/相关的信息,尽管我发表了与后者类似的帖子,一旦该帖子获得批准,我将在此处链接。
对于如何进一步解决或解决问题的任何建议/见解,我们将不胜感激。谢谢!
我刚刚更新到新的Xcode 8,但当我运行我的应用程序时,它提供了很多控制台信息" 只有当我插入iOS + 10设备或iPhone 7模拟器 "但由于新的信息而没有显示所需的日志日志显示如下:
