Sheet inside ForEach doesn't loop over items SwiftUI

There should be only one sheet, so here is possible approach - use another sheet modifier and activate it by selection

Tested with Xcode 12 / iOS 14 (iOS 13 compatible)

extension Int: Identifiable {    public var id: Int { self }}struct ContentView: View {    @State private var selectedMovie: Int? = nil    var movies = ["Harry potter", "Mad Max", "Oblivion", "Memento"]    var body: some View {        NavigationView {            List {                ForEach(0 ..< movies.count) { movie in                    HStack {                        Text(self.movies[movie])                        Image(systemName: "heart")                    }                        .onTapGesture {                            self.selectedMovie = movie                    }                }            }            .sheet(item: self.$selectedMovie) {                Text(self.movies[$0])            }        }    }}

I changed your code to have only one sheet and have the selected movie in one variable.

extension String: Identifiable {    public var id: String { self }}struct ContentView: View {    @State private var selectedMovie: String? = nil        var movies = ["Harry potter", "Mad Max", "Oblivion", "Memento"]    var body: some View {        NavigationView {            List {                ForEach(movies) { movie in                    HStack {                        Text(movie)                        Image(systemName: "heart")                    }                    .onTapGesture {                        self.selectedMovie = movie                    }                }            }            .sheet(item: self.$selectedMovie, content: { selectedMovie in                Text(selectedMovie)            })        }    }}

Wanted to give my 2 cents on the matter.I was encountering the same problem and Asperi's solution worked for me.BUT - I also wanted to have a button on the sheet that dismisses the modal.

When you call a sheet with isPresented you pass a binding Bool and so you change it to false in order to dismiss.What I did in the item case is I passed the item as a Binding. And in the sheet, I change that binding item to nil and that dismissed the sheet.

So for example in this case the code would be:

var movies = ["Harry potter", "Mad Max", "Oblivion", "Memento"]var body: some View {    NavigationView {        List {            ForEach(0 ..< movies.count) { movie in                HStack {                    Text(self.movies[movie])                    Image(systemName: "heart")                }                    .onTapGesture {                        self.selectedMovie = movie                }            }        }        .sheet(item: self.$selectedMovie) {            Text(self.movies[$0])            // My addition here: a "Done" button that dismisses the sheet            Button {                selectedMovie = nil            } label: {                Text("Done")            }        }    }}
