don't know how you get this to compile, but rename "loginButton" to "body".

"body" is a required computed property for the View protocol. Have a look at this doc: https://developer.apple.com/documentation/swiftui/view does it work with "body"? – workingdog support Ukraine Jul 06 '21 at 08:55
This is the above code var body: some View { ZStack(alignment: .top) { self.backgroundImage VStack { self.loginButton } } } – vipinsaini0 Jul 06 '21 at 09:37
@Vipin Saini, I do not know what you are talking about. I have included the code I use for my tests. Does this work for you? – workingdog support Ukraine Jul 06 '21 at 10:07
