Set Language translation (String localisation) in Swift

Set Language

Sometimes we need to make application for various language due to that reason we need to write string file in key value pair.

for this, we need to follow some steps.

1: create new string file name: Localizable.strings file.

2: select project from a project and set localization language like English, Arabic. (Actually, when you set language in swift it will create directory for each language like English: en.lproj file for each)

3: Now you create the global class that will access from any class.

4: write this function.

func language() {
        let languageCode = UserDefaults.standard
        if languageCode.object(forKey: "language") != nil {
            let language = languageCode.object(forKey: "language")
            var path :String = Bundle.main.path(forResource: language as! String?, ofType: "lproj")!
            if path .isEmpty {
                path = Bundle.main.path(forResource: "en", ofType: "lproj")!
            }
            languageBundle = Bundle(path: path)
        }
        else {
            languageCode.set("en", forKey: "language")
            languageCode.synchronize()
            let language = languageCode.string(forKey: "language")!
            var path = Bundle.main.path(forResource: language, ofType: "lproj")!
            if path .isEmpty {
                path = Bundle.main.path(forResource: "en", ofType: "lproj")!
            }
            languageBundle = Bundle(path: path)
        }
    }

func language() {

let languageCode = UserDefaults.standard

if languageCode.object(forKey: "language") != nil {

let language = languageCode.object(forKey: "language")

var path :String = Bundle.main.path(forResource: language as! String?, ofType: "lproj")!

if path .isEmpty {

path = Bundle.main.path(forResource: "en", ofType: "lproj")!

}

languageBundle = Bundle(path: path)

}

else {

languageCode.set("en", forKey: "language")

languageCode.synchronize()

let language = languageCode.string(forKey: "language")!

var path = Bundle.main.path(forResource: language, ofType: "lproj")!

if path .isEmpty {

path = Bundle.main.path(forResource: "en", ofType: "lproj")!

}

languageBundle = Bundle(path: path)

}

5: Now, time to access the file, here I have set for one language you can create for multiple languages by setting their code in (languageCode).

6: Write this function from any class

Here is code snippet:

globalObjectHome.language();
        self.title = self.globalObjectHome.languageBundle.localizedString(forKey: "home", value: "", table: nil);

1 2	globalObjectHome.language(); self.title = self.globalObjectHome.languageBundle.localizedString(forKey: "home", value: "", table: nil);
