How to pass one SwiftUI View as a variable to another View struct

Question

I\'m implementing a very custom NavigationLink called MenuItem and would like to reuse it across the project. It\'s a struct that conforms to Vie

To sum up everything I read here and the solution which worked for me and on iOS14:

struct ContainerView: View {
    let content: Content

    init(@ViewBuilder content: @escaping () -> Content) {
        self.content = content()
    }
    
    var body: some View {
        content
    }
}

This not only allows you to put simple Views inside, but also, thanks to @ViewBuilder, use if-else and switch-case blocks:

struct SimpleView: View {
    var body: some View {
        ContainerView {
            Text("SimpleView Text")
        }
    }
}

struct IfElseView: View {
    var flag = true
    
    var body: some View {
        ContainerView {
            if flag {
                Text("True text")
            } else {
                Text("False text")
            }
        }
    }
}

struct SwitchCaseView: View {
    var condition = 1
    
    var body: some View {
        ContainerView {
            switch condition {
            case 1:
                Text("One")
            case 2:
                Text("Two")
            default:
                Text("Default")
            }
        }
    }
}

Bonus: If you want a greedy container, which will claim all the possible space (in contrary to the container above which claims only the space needed for its subviews) here's it:

struct GreedyContainerView: View {
    let content: Content

    init(@ViewBuilder content: @escaping () -> Content) {
        self.content = content()
    }
    
    var body: some View {
        Color.clear
            .overlay(content)
    }
}
