lproj file not loaded yet

Question

I have created 3 files with translations:

• localizable.strings (English)
• localizable.strings (Swedish)
• localizable.strings (Finnish)

And I have this method to get string by key:

static func localized(key: String) -> String? {
        if let path = Bundle.main.path(forResource: currentLanguage, ofType: "lproj") {
            if let bundle = Bundle(path: path) {
                return NSLocalizedString(key, tableName: nil, bundle: bundle, value: "", comment: "")
            }
        }

        return nil;
    }

but I got "NSBundle < /var/containers/Bundle/Application/213B1469-9751-4459-ABED-80879B80EFBE/Dicken.app/en.lproj> (not yet loaded)"

Why isn't it loaded and where is the problem?

Answer 1

Made extension As this

extension String {
func localized(lang:String) -> String {

    let path = Bundle.main.path(forResource: lang, ofType: "lproj")
    let bundle = Bundle(path: path!)

    return NSLocalizedString(self, tableName: nil, bundle: bundle!, value: "", comment: "")

}

let label: UILabel
var language: String?
label.text  = “Hello”.localized(lang:  self.language! )
