Simple way to localize your String. I don't know why, but somehow I hate alway entering this NSLocalizedString methods. Do your stuff easy with this extension by just "localize your string".localize()

String+Localization.swift

extension String {
    func localize() -> String {
        return NSLocalizedString(self, comment: "")
    }
    
    func localize(_ args: CVarArg...) -> String {
        return String(format: NSLocalizedString(self, comment: ""), args)
    }
}

func localizeSomeString() {
    "This is the localization key".localize()
    "This %@ should be localized in %@ languages.".localized("string", 4)
}
