I have a Set Model:

@Model
class Set: Identifiable{
    var id: UUID
    var weight: Int
    var reps: Int
    var isCompleted: Bool
  //  var exercise: Exercise?       //it can belong to a work but it doesnt have to
    
    init(id: UUID, weight: Int, reps: Int,isCompleted: Bool) {
        self.id = id
        self.weight = weight
        self.reps = reps
        self.isCompleted = isCompleted
    }
    
}

And I am going to allow the user to edit a bunch or list Items based on a temporary array of Sets and when the user is done they sets array will be written to the passed Exercise objects sets array, For now I am using a binding in the ForEach because I want the Textfields to directly control the current object as soon as something is typed into it.

The code:

@Environment(.modelContext) var modelContext
@Environment(.dismiss) var dismiss

var exercise: Exercise

//The user will temporarily write to this sets array than after he is done we will save it to exercises
@State private var sets: [Set] = [Set(id: UUID(), weight: 0, reps: 0,isCompleted: false),Set(id: UUID(), weight: 0, reps: 0, isCompleted: false)]

                        Image(

                                "circle"

                        //Button to dublicate the current set and add it to the list
                        Button {
                            let weight = $set.weight
                            let reps = $set.reps
                            let newSet = Set(id: UUID(),weight: weight, reps: reps, isCompleted: false)
                            sets.append(newSet)
                            
                        }
                        label: {
                            Image(systemName: "plus.rectangle.on.rectangle")
                        }
                    }
                }
                Section {
                    Button{
                        //Adding a New Set to the Temporary Array
                        let newSet = Set(id: UUID(), weight: 0, reps: 0,isCompleted: false)
                        sets.append(newSet)
                    }label: {
                        Text("Add set")
                            .fontWeight(.semibold)
                            .underline()
                    }
                }
            }
            .listStyle(.insetGrouped)

The issue comes in this code and it says : Cannot convert value of type ‘Binding’ to expected argument type ‘Int’

                //Button to dublicate the current set and add it to the list
                Button {
                    let weight = $set.weight
                    let reps = $set.reps
                    let newSet = Set(id: UUID(),weight: weight, reps: reps, isCompleted: false)
                    sets.append(newSet)
                    
                }
                label: {
                    Image(systemName: "plus.rectangle.on.rectangle")
                }

How do you allow Textfield to directly manipulate the data in the current iteration of the List without needing temporary variable and “done” buttons
