I have a Xamarin.Forms project and there are also some .a libs(`C++`) referenced in Xamarin.iOS project.

```
Xamarin.Forms project

  ------codes

Xamarin.iOS project

  ------codes

  ------.a libs(c++)

```

I do have the **source code** of those .a `C++` libs.

The question is that is there a way that I can debug the C++ source code when running the Xamarin.forms project?

**Update**:

I just followed [this document](https://learn.microsoft.com/en-us/xamarin/ios/troubleshooting/questions/debugging-with-xcode) and the Xcode does not attach to the Xamarin app when it launches. Any idea?
