Fixed Size

extension Element {
  func fixedSize(axis: AxisSet = [.horizontal, .vertical]) -> Element
}

The fixed size modifier proposes the child view an infinite size, allowing it to expand freely to its intrinsic size without any constraints. By specifying an axis, the modifier applies infinity along that single axis.

var body: Layout {
  VStack {
    label1
      .frame(width: 100, height: 100)
    label2
      .fixedSize()
      .frame(width: 100, height: 100)
  }
}

In the snippet above, The label2 will be sized to its intrinsic size, ignoring frame 100x100. See the image below for the resulting layout:
