SwiftUI multicolor and multipurpose textfield

Have a problem here, trying to achieve such functionality as on screen shot.
As you can see, there is 2 types of interaction.

1. User can tap on time, like 15 minutes, and a TimePicker will appear. And on weekday – another view will appear.
2. User can tap on purpose and input his own text between ‘on’ and ‘each’ words. Like usual, keyboard will appear, cursor appears – user is ready to input his text in place. ‘answering questions on stackoverflow’ becomes just a placeholder.

It not hard to implement this using just Text, like this one:

Group {
                Text("I would like to spend ")
                    .foregroundColor(.primary) +
                Text("15 minutes")
                    .foregroundColor(.pink)
                    .underline() +
                Text(" on ")
                    .foregroundColor(.primary) +
                Text("answering questions on stackoverflow")
                    .foregroundColor(.teal)
                    .underline() +
                Text(" each ")
                    .foregroundColor(.primary) +
                Text("weekday")
                    .foregroundColor(.green)
                    .underline()
            }

But in such case there is no way to add interactivity, like taps and Text input.

The other way can be probably handled with Markdown?

Thanks for advance.
