The look canvas the thing is isn’t just an approximation of one's person interface — it’s your live app. And Xcode can swap edited code right with your Reside application utilizing dynamic replacement.

So, add these two modifiers to the internal VStack, telling SwiftUI to detect The entire team working with our id house, and animate its include and removing transitions with a slide:

The issue now is always that SwiftUI doesn’t like source us modifying our plan’s point out proper inside of our watch structs without having warning – it wishes us to mark the many mutable state beforehand, so it understands to Look ahead to adjustments.
