Picker not changing

hey y'all, how come this super simple code is not working for me? If I select a different unit in the Picker, it doesn't change its label

import SwiftUI

struct ContentView: View {
    
    let unitList = ["Centimeters", "Meters", "Kilometers", "Inches", "Feet", "Yards", "Miles"]
    @State private var unitDestination = "Meters"

    var body: some View {
        NavigationView {
            Form {
                Section {
                    Picker("Destinated Unit", selection: $unitDestination) {
                        ForEach(0..<unitList.count, id: \.self) { value in
                            Text(unitList[value])
                        }
                    }
                }
            }
        }
    }
}

import SwiftUI

struct ContentView: View {
    
    let unitList = ["Centimeters", "Meters", "Kilometers", "Inches", "Feet", "Yards", "Miles"]
    @State private var unitDestination = "Meters"

    var body: some View {
        NavigationView {
            Form {
                Section {
                    Picker("Destinated Unit", selection: $unitDestination) {
                        ForEach(0..<unitList.count, id: \.self) { value in
                            Text(unitList[value])
                        }
                    }
                }
            }
        }
    }
}

Solution:

changed it to ```swift Picker("Original Unit", selection: $unitOriginal) { ForEach(unitList, id: .self) { unit in Text(unit)...

changed it to

Picker("Original Unit", selection: $unitOriginal) {
                        ForEach(unitList, id: \.self) { unit in
                            Text(unit)
                        }
                    }

Picker("Original Unit", selection: $unitOriginal) {
                        ForEach(unitList, id: \.self) { unit in
                            Text(unit)
                        }
                    }
