Apple's own SwiftUI tutorial help! : iOSProgramming



I'm trying to learn SwiftUI using this Apple tutorial. When I try the same code building succeed but I can't see the preview, I'm new to programming and can't find what I'm doing wrong.

Is it because of SwiftUI, macOS 10.15, Xcode 11 is still in beta 196
