I'm creating an app that contains ingredients for foods (simplified version of the app for context of the question). However, I am not sure how to updates values of an array (ingredients).

I have the following struct for each Food that contains a ID(UUID), a name(string), and ingredients(array). I've created a master view for each food as a @State variable and then a detail view which has an edit button that takes you to an edit view with the selected food as a @Binding var.

public struct Food: Hashable, Codable, Identifiable, { public var id = UUID()

var name: String
var ingredients: Array<String>

}

In the edit view I'm able to update the name of the food but I can't figure out how to update each individual ingredient. This is the line giving me trouble in the edit view:

ForEach(food.ingredients, id: \.self) { ingredient in
    List {
        TextEditor($ingredient)
                                        
    }
}

Any help would be much appreciated.

what is the issue? you can't edit ingredients or can't figure out how to store value in array? – Pratik Prajapati Apr 17 '21 at 05:59

You'll need to iterate over indices with `ForEach(food.ingredients.indices, id: \.self) { ... }` and then use `$food.ingedients[index]` as a binding to pass to `TextEditor` – New Dev Apr 17 '21 at 06:01
@PratikPrajapati Yes I can't edit the ingredients. I'm not sure how to edit an array stored in a struct. – tyleroki Apr 17 '21 at 06:02
try mutating func in struct. – Pratik Prajapati Apr 17 '21 at 06:03
@NewDev That's it! Appreciate it – tyleroki Apr 17 '21 at 06:25
