I'm trying to change the locale of an app with Picker as follows.
import SwiftUI
@main
struct LocaleSwitchCrazyMamaApp: App {
var body: some Scene {
WindowGroup {
let lanSetting = LanguageSetting()
ContentView()
.environmentObject(lanSetting)
.environment(\.locale, lanSetting.locale)
}
}
}
class LanguageSetting: ObservableObject {
@Published var locale = Locale(identifier: "en")
}
import SwiftUI
struct ContentView: View {
@State private var segmentSelection = 0
@EnvironmentObject var languageSetting: LanguageSetting
var body: some View {
VStack {
Text(NSLocalizedString("Hello", comment: ""))
.padding(.vertical, 20)
Picker("Language", selection: $segmentSelection) {
Text("English").tag(0)
Text("Japanese").tag(1)
Text("French").tag(2)
}
.frame(width: 200)
.pickerStyle(.segmented)
.onChange(of: segmentSelection) {newValue in
if newValue == 0 {
languageSetting.locale = Locale(identifier: "en")
} else if newValue == 1 {
languageSetting.locale = Locale(identifier: "ja")
} else {
languageSetting.locale = Locale(identifier: "fr")
}
}
}
.padding()
}
}
In addition, I have three locale versions like the following
"Hello" = "Hello"; // en.lproj
"Hello" = "Bonjour"; //fr.lproj
"Hello" = "こんにちは"; // ja.lproj
As long as I run the app on a simulator, the language of the Hello text won't change when tap any of the segments. What am I doing wrong?
Muchos thankos
