我决定尝试学习如何制作iOS应用。我是一台旧的MacBook Pro，我已经安装了Xcode 7.3，我认为这是我可以在CPU上使用的最新版本。
我决定遵循这个基本教程：
换句话说，我创建一个项目并创建一个单一的视图应用程序，然后我尝试查看它。我没有写任何代码。我只是试图运行Xcode自动生成的代码。
但是Xcode创建的代码没有运行。当模拟器出现时，它会变黑一段时间，然后是白色。当我打开控制台时，我看到了数百个错误。以下是一些更有趣的内容：

Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

那么，我该如何调试呢？我再次没有写任何代码。我只是试图运行Xcode自动生成的代码。但它没有运行。
我提出了很多问题，但在很多方面，最后一行是什么？
tcp_connection_tls_session_error_callback_imp
为什么这个简单的应用需要TCP连接？既然如此，为什么TCP连接失败？
