How to prevent Text from expanding the width of a VStack

Question

I have a VStack that contains an Image and a Text. I am setting the width (and height) of the Image to be half of the screen's width:

struct PopularNow: View {
    let item = popular[0]
    
    var body: some View {
        VStack(spacing: 5) {
            Image(item.image)
                .resizable()
                .aspectRatio(contentMode: .fit)
                .frame(width: getRect().width/2, height: getRect().width/2)
            Text(item.description)
                .font(.caption)
                .fontWeight(.bold)
                .lineLimit(0)
        }
        .padding()
        .background(Color.gray.opacity(0.1))
        .cornerRadius(15)
    }
    
    func getRect() -> CGRect {
        return UIScreen.main.bounds
    }
}

The problem is that the Text pushes and causes the VStack to expand instead of respecting the Image's width. How can I tell the Text to not grow horizontally more than the Image width and to grow "vertically" (i.e. add as many lines it needs)? I know that I can add the frame modifier to VStack itself, but it seems like a hack. I want to tell the Text to only take as much space width wise as VStack already has, not more.

This is what it looks like right now, as you can see the VStack is not half the screen's size, it's full screen size because the Text is expanding it.

Why are you specifying .lineLimit(0). According to documentation, if you don't want a limit, you should pass nil - .lineLimit(nil), which I think is the default anyway — New Dev

@swiftPunk something like priorities in UIKit. That type of logic... — az2902

Try to fix its size, like

    VStack(spacing: 5) {
        Image(item.image)
            .resizable()
            .aspectRatio(contentMode: .fit)
            .frame(width: getRect().width/2, height: getRect().width/2)
        Text(item.description)
            .font(.caption)
            .fontWeight(.bold)
            .lineLimit(0)
    }
    .fixedSize()         // << here !!
//   .fixedSize(horizontal: true, vertical: false)   // alternate
    .padding()
