Make a VStack fill the width of the screen in SwiftUI

Problem Statement
In SwiftUI, a VStack (Vertical Stack) does not automatically expand to fill the entire width of the screen. Instead, it adopts the size of its children, resulting in a layout that is only as wide as the widest child. This behaviour can cause alignment issues or undesired spacing in your UI when you want the VStack to span the full width of the screen.
VStack { Text("Short Text") Text("Another Line of Text")}.background(Color.red) Desired Outcome
The VStack should expand to fill the full width of the parent container or screen, ensuring any background or styling applies across the full width, irrespective of the size of its children.
Solution
We can extend the Color struct in SwiftUI with convenience methods to create colors from hex values.
VStack {Text("Short Text") .padding() .background(Color.blue) Text("Another Line of Text") .padding() .background(Color.green)}.frame(maxWidth: .infinity) // Expand VStack to full width.background(Color.red) // Background spans full width
