Create a Picker that returns a String - swift

Question

Hello everyone
I am creating a form that allows me to modify the data of #EnvironmentObject variable.
Therefore, I would like to be able to create a Picker that returns a String. However, after many unsuccessful attempts, I have the impression that a Picker cannot return a String.
Anyone would have an idea for a Picker that returns a String (maybe through UIKit ?).
Here's my code :
struct UserStruct {
var firstName: String
var lastName: String
var birthDate: Int
var city: String
var postalCode: Int
var street: String
var streetCode: String
var country: String
}
class User: ObservableObject {
#Published var userProfile = UserStruct()
// Other stuff here
}
// Then in my FormView:
// I declare the object as #EnvironmentObject
#EnvironmentObject var userStore: User
// I declare an array which contains all the country for the picker
let country = ["France", "Russie", "USA"]
// In my var body: some View...
// Trying to change the value of country of the userStore object
Picker(selection: $userStore.userProfile.country, label: Text("Make a choice")) {
ForEach(0 ..< country.count) { index in
Text(self.country[index]).tag(index)
}
Thank you all for your help.

Answer 1

you could try something like this:
let country = ["France", "Russie", "USA"]
#State var countrySelection = 0
Picker(selection: Binding(get: {
self.countrySelection
}, set: { newVal in
self.countrySelection = newVal
self.userStore.userProfile.country = self.country[self.countrySelection]
}), label: Text("Make a choice")) {
ForEach(0 ..< country.count) { index in
Text(self.country[index]).tag(index)
}
}
