import SwiftUI

struct ContentView: View {
    var body: some View {
        MyView()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

struct MyView: View {
    var action: (() -> Void)?
    
    var body: some View {
        Text("MyView")
            .onTapGesture {
                action?()
            }
    }
    
    func setAction(_ action: @escaping () -> Void) -> MyView {
        var copy = self
        copy.action = action
        return copy
    }
}

struct LibraryContent: LibraryContentProvider {
    func modifiers(base: MyView) -> [LibraryItem] {
        [
            LibraryItem(
                base.setAction {
                    
                },
                title: "MyView - Set action"
            )
        ]
    }
}

When passing an empty closure to a LibraryItem's snippet parameter, unexpected extra text is added to the file when the item is dragged in from the Xcode library.

Expected:

.setAction {
    
}

Actual:

.setAction /*@START_MENU_TOKEN@*/{
    
}/*@END_MENU_TOKEN@*/
