How to download language packs from Google Translate Api or cloud translation api for offline usage?

I am trying to build a translator application in swift and for that I have decided to go with Google Translate Api. I was searching for ways to provide user with offline translation functionality. I was unable to find any documentation about the same.

Can anyone help me explore more on this issue and how to achieve it?

I believe you need to download the language files.

Have a look at this google translate Download languages to use offline

After a bit of research Google provide some thing called on-device translation. ML Kit's on-device translation API

According to the documentation you can download the files following 

// Download the French model.
let frModel = TranslateRemoteModel.translateRemoteModel(language: .fr)

// Keep a reference to the download progress so you can check that the model
// is available before you use it.
progress = ModelManager.modelManager().download(
    frModel,
    conditions: ModelDownloadConditions(
        allowsCellularAccess: false,
        allowsBackgroundDownloading: true
    )
)

And to translate 

englishGermanTranslator.translate(text) { translatedText, error in
    guard error == nil, let translatedText = translatedText else { return }

    // Translation succeeded.
}
