ViewBuilder

The SwiftUI code provided in the markdown document demonstrates two ways to create a vertical stack of views containing two Text views.

In the first example, the code is written in a more concise manner:

VStack {
    Text("AAA")
    Text("BBB")
}

The second example is a more explicit representation of the same code:

VStack.init(content: {
    ViewBuilder.buildBlock(
        Text("AAA"),
        Text("BBB")
    )
})

Both examples achieve the same result.
