Creating a View that contains another view builder in SwiftUI

ContainerView.swift

import SwiftUI

struct ContainerView<Content: View>: View {
    
    let content: Content

    public init(@ViewBuilder builder: () -> Content) {
      self.content = builder()
    }

    public var body: some View {
        content
    }
}

// Usage
struct ContainerView_Previews: PreviewProvider {
    static var previews: some View {
        ContainerView() { Text("hi") }
    }
}
