Select Multiple Items in SwiftUI List

Question

In UIKit you can select multiple rows of a UITableView by using allowsMultipleSelection - can this be done with the List in SwiftUI?

Answer 1

my 2 cents with a super simple solution:

import SwiftUI

struct ListDemo: View {
    @State var items = ["Pizza", "Spaghetti", "Caviar"]
    @State var selection = Set()
    
    var body: some View {
        List(items, id: \.self, selection: $selection) { (item : String) in
            
            let s = selection.contains(item) ? "√" : " "
            
            HStack {
                Text(s+item)
                Spacer()
            }
            .contentShape(Rectangle())
            .onTapGesture {
                if  selection.contains(item) {
                    selection.remove(item)
                }
                else{
                    selection.insert(item)
                }
                print(selection)
            }
        }
        .listStyle(GroupedListStyle())
    }
}

using string in set is sub-optimal, better to use id OR using strict with data and selection state.
