Game Development in SwiftUI

I want to develop games using swiftUi. I develop games in Unity. Now I want to learn to develop games in SwiftUI.
I have few queries:
1: How can we animate objects in SwiftUI?
2: How can we add background?
3: How can we move objects?
I will be glad if you answer my queries. I will be waiting for your response. Thanks
