title: Scroll to specific section and item in SwiftUI list
body: <p>I have a <code>List</code> with 12 sections that represent the months of a year and each seach has the number of days of a month as an item. The problem is <code>ScrollViewReader</code> only scrolls the items of the first section. for example, January contains 31 days and it works when I call <code>scroll.scrollTo(23, anchor: .center)</code>. How can I make scrollView scroll to a specific section 5 (June) and item 9 (today)?. Here is my code:</p>
  <pre><code>let daysInMonth = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30 ,31]
  
      ScrollViewReader { scroll in 
  
      List {
          Section(&quot;January&quot;) {
              ForEach(0..&lt;daysInMonth[0], id:\.self) {
                  CalendarRow(calendar: fetchCalendarData(section: 0, index: $0))
              }
          }
  .
  .
  .
  // and other sections to December
  
      }
  }
  
  .onAppear {
                  withAnimation { scroll.scrollTo(ROW, anchor: .center) }
              }
  </code></pre>
