- If your layout has one dominant view that defines the size of the layout, use the
overlay(_:alignment:)
or background(_:alignment:)
view modifier on that view.
- If you want the final view size to come from an aggregation of all the contained views, use a
ZStack
.

the offset(x:y:)
modifier uses the parameters of x and y to represent a relative location within the view’s coordinate space.
ZStack 沒有指定 alignment,所以 Image 會在正中間(80,80)。 .offset(x: 40.0, y: -40.0)
加上這個偏移的話,就會坐落在第一象限。

and Text
views.
