ios - 哪里有对 iOS 和 Mac OS X 网络错误(如 kCFStreamErrorDomainSSL)的清晰、完整的引用？

Question

在 Xcode 中调试网络代码时，我经常遇到如下错误序列:

NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802)

我研究这些错误的努力都没有找到对它们的引用，因此我可以按顺序调试它们，而无需对每个单独的错误进行研究。

经过大量搜索，我发现 Apple 自己的引用页面没有链接到相应的错误编号。然后我能够在源代码中找到适当的错误列表和枚举:

TL;DR 没有网页(现在除了这个)有单词 kCFStreamErrorDomainSSL 和错误编号，甚至没有 Apple 引用页面。
