So, increase these two modifiers to your inner VStack, telling SwiftUI to discover the whole group applying our id house, and animate its add and elimination transitions which has a slide:
The good news is, SwiftUI allows us nest stacks freely, that means that we can position a VStack inside A different VStack to get the precise habits we want. So, modify your code to this:
In the event you increase a number of spacers, they are going to divide the space Similarly among them. If you try inserting a second spacer ahead of the “Why not check out…” text you’ll see what I mean – SwiftUI will make and equivalent volume of space higher than the text and down below the activity identify.
