Multi-Line Text in a NavigationButton in a List

You could try adding .multilineTextAlignment(.leading||center||trailing) and see if that triggers it to render properly. That worked for me in a few similar cases.

I also have this probelm, except with an HStack - text (a number), text (most of the row), and a button on the right. The text in the middle should have a line limit of 3, but it always remains on one line and weirdly stretches/warps the text size (still truncating with ...). I've yet to find a solution to that, and it seems kinda like an extension of the issue you're describing.

Edit: Adding the modifier .layoutPriority(1) to my big text view fixed that issue, in case that helps at all.
