Setting “AppleLanguages” doesn't change app language

Question

I am trying to implement a function that can change app language.
I tried to set it like this:

let defaults = NSUserDefaults.standardUserDefaults()
defa         


        

Answer 1

Updated Swift syntax of the main.swift file mentioned in @royherma's answer. This will avoid having to restart the app after overriding the UserDefaults settings:

import Foundation
import UIKit

// Your initialization code here
let langCultureCode: String = "LANGUAGE_CODE"

UserDefaults.standard.set([langCultureCode], forKey: "AppleLanguages")
UserDefaults.standard.synchronize()

UIApplicationMain(CommandLine.argc, CommandLine.unsafeArgv, nil, NSStringFromClass(AppDelegate.self))

paired together with the removal of @UIApplicationMain in your AppDelegate.swift file.
