UIKit support floating section headers This is enabled by default for UITableView and is optional for UIColklectionView See: sectionHeadersPinToVisibleBounds

How can I accomplish the same behaviour in SwiftUI?

You can set the header in an HStack before the List. You just need to make sure the rows have the same width (first row of title has same width as first row in the list)

VStack(alignment: .center) {
  HStack {
    Text("Header 1").frame(width: 100)
    Text("Header 2").frame(maxWidth: .infinity)
  }
  List {
    ForEach(0..<data.count) { num in
      HStack {
        Text("Row 1-\(num)").frame(width: 100)
        Text("Row 2-\(num)").frame(maxWidth: .infinity)
      }
    }
  }
}

That's one solution. I don't know if there's a native one.

Thanks for the response!

Unfortunalty your example does not provide a sollution for multiple sections

What I need is the default UITableView behaviour

Have a look at the iOS contacts app to see what I mean

Scroll through the contacts and watch the section header below the search field

I understand. Have you tried playing around with Section? Maybe SwiftUI 2.0 will come with good news theron that front. I haven't checked.
