问题 I need to display some text in a SwiftUI Form that will change depending on the current state. However, if the "new" text is longer than the original string displayed when the form first appeared, it won't wrap correctly. In the example below, turning the toggle on changes the text being displayed, but it gets truncated instead of wrapping struct ContentView: View { @State var showLongString = false var body: some View { Form { Section { Text(showLongString ? "This is a string that is too

问题 Lately, I have been working on creating a complex view that allows me to use a Picker below a Form. In every case, the Form will only have two options, thus not enough data to scroll downwards for more data. Being able to scroll this form but not Picker below makes the view feel bad. I can't place the picker inside of the form or else SwiftUI changes the styling on the Picker. And I can't find anywhere whether it is possible to disable scrolling on a List/Form without using: .disable
