Thankfully, SwiftUI allows us nest stacks freely, which means that we could location a VStack inside of An additional VStack to have the precise habits we want. So, modify your code to this:

right, but it'll really trigger compiler problems. We’re telling Swift to pick a random element from the array and area it into the chosen home, but there’s no way for Swift To make sure there’s everything in that array – it could be vacant, during which scenario there’s no random element to return.

, and there’s a totally free app you could obtain that exhibits you all the options. Each individual of those icons is obtainable in multiple weights, may be scaled up or down efficiently, and lots of can also be coloured.
