Description

I needed line wrap with TextField, not multiline input. Just when 1 long line of text is entered I want to see it all and not truncate, i.e. have the field expand vertically.

When I use TextField with axis: .vertical I have a problem with the iOS software keyboard e.g. iPhone Simulator if I press return on that then it adds a new line. However if I press return on my Mac's hardware keyboard it submits the field as expected. I would like the iPhone software keyboard to submit the field the same as the mac's keyboard thanks. If I wanted newlines to be entered then I would be using TextEditor not TextField. I am only after the line wrapping functionality so that when a long line of text is entered it will wrap and it can expand vertically.

I also tested a physical iPhone 16 pro 18.5 and has the same issue as the sim

Xcode Version 16.4 (16F6) simulator 18.5

                TextField("Enter Text",
                          text: $text,
                          prompt: Text(title).foregroundStyle(isFocused ? AnyShapeStyle(.foreground) : AnyShapeStyle(.tint)),
                          axis: .vertical
                )
               .submitLabel(.done)

screen cap attached. the done button should submit not add new lines

SwiftUI.VerticalTextView
