Thankfully, SwiftUI lets us nest stacks freely, this means that we could spot a VStack inside A different VStack to have the precise behavior we would like. So, alter your code to this:

right, but it'll truly lead to compiler faults. We’re telling Swift to pick a random element in the array and spot it into the selected house, but there’s no way for Swift to be sure there’s everything in that array – it may be vacant, where scenario there’s no random aspect to return.

as opposed to needing to edit the code every time, so we’re likely to incorporate a button down below our inner VStack that can find here adjust the chosen exercise each time it’s pressed.
