控制台将显示模拟器中运行的应用程序的 NSLog（）输出。崩溃日志保存到文件中。

The console will show the NSLog() output from an app running in the simulator. The crash logs are saved to file.

我在我的主目录下找到了一些

I have found some in my home directory under

~/Library/Logs/DiagnosticReports/

他们的文件扩展名为 .crash

我还没想到的是，即使调试器抓住了它，如何让它们生成 EXC_BAD_ACCESS signal。

Something I haven't yet figured out is how to get them to generate even if the debugger grabs the EXC_BAD_ACCESS signal.

更新

目前，（OSX 10.11.6），.crash登录〜/ Library / Logs / DiagnosticReports ，当模拟器本身崩溃时。 app 崩溃的日志（但模拟器设备仍然运行良好），位于：

Currently, (OSX 10.11.6), the .crash logs in ~/Library/Logs/DiagnosticReports, are when the emulator itself crashes. Logs for an app crashing (but the emulator device is still running fine), are in:

〜/ Library / Logs / CoreSimulator

~/Library/Logs/CoreSimulator

每次崩溃时，都有一个具有唯一ID的子文件夹。按日期排序，以便您最近的崩溃是第一个子文件夹。在其中，首先查看 stderr.log 和 system.log 。

Per crash, there is a sub-folder with a unique id. Sort by date, so that your recent crash is the first sub-folder. Inside that, start by looking at stderr.log and system.log.

也直接在 CoreSimulator 下，参见 CoreSimulator.log 和模拟器。记录。
