swift - How do you create a multi-line text inside a ScrollView in SwiftUI?

Question

Since List doesn't look like its configurable to remove the row dividers at the moment, I'm using a ScrollView with a VStack inside it to create a vertical layout of text elements. Example below:

ScrollView {
    VStack {
        // ...
        Text("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer mattis ullamcorper tortor, nec finibus sapien imperdiet non. Duis tristique eros eget ex consectetur laoreet.")
            .lineLimit(0)
    }.frame(width: UIScreen.main.bounds.width)
}

The resulting Text rendered is truncated single-line. Outside of a ScrollView it renders as multi-line. How would I achieve this inside a ScrollView other than explicitly setting a height for the Text frame ?

Answer 1

In Xcode 11 GM:

For any Text view in a stack nested in a scrollview, use the .fixedSize(horizontal: false, vertical: true) workaround:

ScrollView {
    VStack {
        Text(someString)
            .fixedSize(horizontal: false, vertical: true)
    }
}

This also works if there are multiple multiline texts:

ScrollView {
    VStack {
        Text(someString)
            .fixedSize(horizontal: false, vertical: true)
        Text(anotherLongString)
            .fixedSize(horizontal: false, vertical: true)
    }
}

If the contents of your stack are dynamic, the same solution works:

ScrollView {
    VStack {
        // Place a single empty / "" at the top of your stack.
        // It will consume no vertical space.
        Text("")
            .fixedSize(horizontal: false, vertical: true)

        ForEach(someArray) { someString in
            Text(someString)
              .fixedSize(horizontal: false, vertical: true)
        }
    }
}
