For wrapping Text in a Form .lineLimit(Int.max) did not work for me. It seems there needs to be some width for it to know when to wrap. I believe the official way is with .fixedSize:
Text(message)
.fixedSize(horizontal: false, vertical: true)
The documentation states:
This example shows the effect of fixedSize(horizontal:vertical:) on a text view that is wider than its parent, preserving the ideal, untruncated width of the text view.
