I would like to react on a choice of a user. Something similar to this example:

In a 2nd stage would I like to show additional content below each radiobutton, e.g. moving the buttons 2 and 3 from each other in order to give a list of websites for allowing.

So far I haven't found how to do this in SwiftUI. Many thanks in advance!

Picker(selection: $order.avocadoStyle, label: Text("Avocado:")) { 
    Text("Sliced").tag(AvocadoStyle.sliced) 
    Text("Mashed").tag(AvocadoStyle.mashed)
}.pickerStyle(RadioGroupPickerStyle())

This is the code from the 2019 swiftUI essentials keynote (SwiftUI Essentials - WWDC 2019. Around 43 minutes in the video they show this example.

How to Create Radio Button and Group in SwiftUI, How to create Radio Button's in SwiftUI? Question. This showed up in the Avocado Toast presentation at WWDC 2019  I needed a radio button and a group of radio buttons in my SwiftUI based project. So let me show you how I created a single and group of radio buttons in SwiftUI. You can reuse the code for your purpose as well.

I'm using swift4, Catalina OS and Xcode 11.2 and was having the issue where RadioGroupPickerStyle was unavailable for iOS and .radiogroup just didn't work (it froze in build) so I made my own that's reusable for other occasions. (notice its only the button so you have to handle the logic yourself.) Hope it helps!

import SwiftUI

struct RadioButton: View {
let ifVariable: Bool    //the variable that determines if its checked
let onTapToActive: ()-> Void//action when taped to activate
let onTapToInactive: ()-> Void //action when taped to inactivate

var body: some View {
    Group{
        if ifVariable {
            ZStack{
                Circle()
                    .fill(Color.blue)
                    .frame(width: 20, height: 20)
                Circle()
                    .fill(Color.white)
                    .frame(width: 8, height: 8)
            }.onTapGesture {self.onTapToInactive()}
        } else {
            Circle()
                .fill(Color.white)
                .frame(width: 20, height: 20)
                .overlay(Circle().stroke(Color.gray, lineWidth: 1))
                .onTapGesture {self.onTapToActive()}
        }
    }
}
}

TO USE: Put this in any file and you can use it as you would any other view anywhere else in the project. (we keep a global folder that has a buttons file in it)

Comments
  • What have you tried so far?
  • I am only learning SwiftUI and this is my first need. My first idea was to create it all from Scratch as I cannot find examples. By now I decided to go with Cocoa instead as I cannot wait too long right now. :-(
  • How to Create .radioGroup?
  • It’s a predefined type but it could be renamed to RadioGroupPickerStyle. .pickerStyle(RadioGroupPickerStyle())
  • 'RadioGroupPickerStyle' has been explicitly marked unavailable here (SwiftUI.RadioGroupPickerStyle) I am getting above error
  • I think radio buttons are not natively supported for iOS.
  • Please note that RadioGroupPickerStyle is supported on Mac only (so no iOS)
