Better yet, we will Manage how that add and remove transition comes about using a transition() modifier, which has various designed-in transitions we could use.

Thankfully, SwiftUI lets us nest stacks freely, this means that we will position a VStack inside One more VStack to find the exact behavior we would like. So, alter your code to this:

Rather than using a fixed font sizing, that takes advantage of one of SwiftUI’s built-in Dynamic Style dimensions named .title. What this means is the font will expand or shrink dependant upon the consumer’s settings, which is generally a good suggestion.
