How to get the progress from WhisperCPP for a percentage value in Swift?

[LeoHeuser]

Hey CPP colleagues,
in a private app project I use whisperCPP to support me during interviews. The system helps me quite a lot and it works super on a iPhone and iPad. I develop it in Swift, SwiftUl and SwiftData.
In this app I have a view called "activeTranscriptionView" that just shows to me that the system is working with a loading spinner.

For a better estimation of my time I want a progress indicator with more value. There I think about a Text with a percentage value (see screenshot). I don't get how the whisperContext can return anything like a progress so I can store it in a var and use it in SwiftUl.

I also saw this parameters

[Code].withCString { language in
          [...]
          params.print_progress = false
          [...]
}

but I also don't know how to access these later on via Swift.

Does anyone of you have an idea how I get the progress from whisperCPP so that I can display it in the Ul? If you need any additional information or input from my side just let me know.

Thanks for you support and best,
Leo 👋🏼
