How do I size a UITextView with scroll disabled?

tl;dr: UITextView does not auto layout when isScrollEnabled = false

I have a screen with multiple UITextViews on it, contained within a ScrollView. For each textview, I calculate the height needed to display the entire content in SwiftUI and set it using the .frame(width:height:) modifier.

The UITextView will respect the size passed in and layout within the container, but since UITextView is embedded within a UIScrollView, when a user attempts to scroll on the page, often they will scroll within a UITextView block rather than the page. They currently need to scroll along the margins outside of the textview to get the proper behavior.

Since I am already calculating the height to display the text, I don't want the UITextView to scroll. However, when I set isScrollEnabled = false, the text view displays in a single long line that gets truncated. I have tried

• Setting various frame/size attributes but that seems to have zero affect on the layout.
• Embedding the textView within a UIView, and then sizing the container, but then the textView does not display at all.
• Setting a fixed size textContainer in the layoutManager but did not work.

There's a lot of code so I can't copy/paste it all, but generally, it looks like

struct SwiftUITextEditor: View {
  @State var text: AttributedString = ""

  var body: some View {
    ZStack {
      MyTextViewRepresentable(text: $text)
    }
    .dynamicallySized(from: $text)
  }
}

struct MyTextViewRepresentable: UIViewRepresentable {
  @Binding var text: AttributedString
  let textView = UITextView(usingTextLayoutManager: true)

  func makeUIView(context: Context) -> UITextView {
    textView.attributedText = text
    textView.isScrollEnabled = false
  }
  ...
}
