20.4 Working with Subviews
Apple recommends that views be kept as small and lightweight as possible. This promotes the creation of reusable components, makes view declarations easier to maintain and results in more efficient layout rendering.
If you find that a custom view declaration has become large and complex, identify areas of the view that can be extracted into a subview. As a very simplistic example, the HStack view in the above example could be extracted as a subview named “MyHStackView” as follows:
struct ContentView: View {
var body: some View {
VStack {
VStack {
Text("Text 1")
Text("Text 2"...
