SwiftUI - Form Picker - How to prevent navigating back on selected? - swift

Question

I'm implementing Form and Picker with SwiftUI. There is a problem that it automatically navigates back to Form screen when I select a Picker option, how to keep it stay in selection screen?
Code:
struct ContentView: View {
#State private var selectedStrength = "Mild"
let strengths = ["Mild", "Medium", "Mature"]
var body: some View {
NavigationView {
Form {
Section {
Picker("Strength", selection: $selectedStrength) {
ForEach(strengths, id: \.self) {
Text($0)
}
}
}
}
.navigationTitle("Select your cheese")
}
}
}

You may have to make a custom view that mimics what the picker looks like:
struct ContentView: View {
let strengths = ["Mild", "Medium", "Mature"]
#State private var selectedStrength = "Mild"
var body: some View {
NavigationView {
Form {
Section {
NavigationLink(destination: CheesePickerView(strengths: strengths, selectedStrength: $selectedStrength)) {
HStack {
Text("Strength")
Spacer()
Text(selectedStrength)
.foregroundColor(.gray)
}
}
}
}
.navigationTitle("Select your cheese")
}
}
}
struct CheesePickerView: View {
let strengths: [String]
#Binding var selectedStrength: String
var body: some View {
Form {
Section {
ForEach(0..<strengths.count){ index in
HStack {
Button(action: {
selectedStrength = strengths[index]
}) {
HStack{
Text(strengths[index])
.foregroundColor(.black)
Spacer()
if selectedStrength == strengths[index] {
Image(systemName: "checkmark")
.foregroundColor(.blue)
}
}
}.buttonStyle(BorderlessButtonStyle())
}
}
}
}
}
}
