Easy Way to handle the String Localization & find the missing key in Localize string file using swift 4

String Localization & find the missing key in Localize string

Most of apps work on various languages , for supporting the various languages we have to take Language string file of respective language .

Here i will provide the full information regarding

a: How to take this file and add to project.

b: Localized using small method.

c: Track all the missing key Value:

The Above “a” point you can cover by this blog:

Set Language translation (String localisation) in Swift

b: Write one Extension

extension String {
    
    var localized: String {
        return GlobalData.sharedInstance.language(key: self)
    }
    
}

extension String {

var localized: String {

return GlobalData.sharedInstance.language(key: self)

}

Note: GlobalData.sharedInstance.language(key: self)

– this is method that will provide the corresponding key value from localize string file.

like home = “Home”;

Here is code Snippet :

func language(key:String) ->String{
        let languageCode = UserDefaults.standard
        if languageCode.object(forKey: "language") != nil {
            let language = languageCode.object(forKey: "language")
            if let path = Bundle.main.path(forResource: language as! String?, ofType: "lproj") {
                languageBundle = Bundle(path: path)
            }
            else{
                languageBundle = Bundle(path: Bundle.main.path(forResource: "en", ofType: "lproj")!)
            }
        }
        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)
        }
        
        return languageBundle.localizedString(forKey: key, value: "", table: nil)
    }

func language(key:String) ->String{

let languageCode = UserDefaults.standard

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

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

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

languageBundle = Bundle(path: path)

}

else{

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

}

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)

}

return languageBundle.localizedString(forKey: key, value: "", table: nil)

}

It will return corresponding value;

Now its time to use this functionality:

Exam:

self.navigationItem.title = “applicationname”.localized

it will set the value of this key from string file – “applicationname”

Now we have to track which string are missing in file , for that we have to do some steps:

1: Open project and follow this:

2: Click on the edit scheme:

a: Click on Arguments and set – “NSShowNonLocalizedStrings YES”

b: Click on option and check on “Localization Debugging”

3: Now its time to Track the missing string in project , after setting all this things you have to just run this project :

Then you will got warning in debug window;

I have taken the example of this:

self.navigationItem.title = “applicationnamee”.localized

I did not localized this key in string file.

so I got warning like this:
