Containers that are the parents in the semantics above, containers that will organize their siblings using said rules. You can then use offset(x:y:) to move the text around inside that frame. To lay out/manage space in SwiftUI, you use containers (ZStack, VStack, and HStack). frame(width: 300, height: 300, alignment.

The VStack is the higher view in the hierarchy, and will align the text on the leading side (left when the language is read from left to right). As the parent doesn’t have a say in the final size of the child, code like this will create a 300x300 frame with a smaller text view centered inside it: Text("Live long and prosper")
