I have a textView that is initially empty and is populated with custom text by pressing buttons. The size of the font is

.dynamicTypeSize(.xxxLarge)

I want to display the text view within a fixed frame surrounded by a border. The problem is when the textview is empty, the frame flattens.

Here is the code of the textview:

                                Text(filtreString)
                                    .padding(6)
                                    .dynamicTypeSize(.xxxLarge)
                                    .frame( maxWidth: .infinity)
                                    .background(Color("fondbleu"))
                                    .border(Color.black, width: 1)
                                    .cornerRadius(20.0)
                                    .overlay(
                                        RoundedRectangle(cornerRadius:20).stroke(.black, lineWidth: 1))

Here is the textview, empty and populated:

It might be quite simple, but I could not find the way to set the height of the view without populating some text inside the textview. I could for example put a space character ” ” but I would like to avoid that because the empty string is one of the possible values.

Can someone help me out ? Thanks !

I tried something like font.lineHeight but the compiler did not seem to like it.
