In version 17.0 or above, there are no recording issues in the object-c project, iPhone and simulators can't start recording, Why?

你好，下面的是项目链接: https://drive.google.com/file/d/108-sTxjT8_YTYMxcH_-DntBO1e3teIln/view?usp=share_link github一直无法传上去，所以项目传到了google云盘，项目解压直接运行--> 点击录制，之后就会在控制看到如上图所示的警告提示，录音无法正常启动录制。有劳了！

Hello @toliv, thank you for your comment. Indeed, there seems to be a bug with the Capturing stereo audio from built-in microphones sample code project. Please use Feedback Assistant to submit a bug report.

One way to work around the bug is by changing line 102 of MainViewController.swift to:

guard controller.isDeviceSupported, controller.state != .recording else { return }

Once you do that, however, you might see the alert declared in line 46 of MainViewController.swift if you run the project on the iOS Simulator.
