Displaying an empty view in SwiftUI

Question

In SwiftUI there\'s frequently a need to display an \"empty\" view based on some condition, e.g.:

struct OptionalText:          


        

Answer 1

You have to return something. If there is some condition where you want to display nothing, "display" an...EmptyView ;)

var body: some View {
    Group {
        if text != nil {
            Text(text!)
        } else {
            EmptyView()
        }
    }
}

The SwiftUI DSL will require you to wrap the if/else in a Group and the DSL has no guard/if let nomenclature.
