Is it possible to get into programming an extension for the control center in Swift? Not something like the widget spotify provides but one level above.
How I have to think about it? Is it neccessary to have an app like "Calculator" so that you can create a button for it in the control center or are there other possibilities like creating a fully fledged app but making it possibly invisible, like "Screen Recorder"?
As far as I know, a collegue of mine showed me some custom stuff but it was available due to a Jailbreak I think.
