Thank you for your contribution!

@lukszar we realized after merging that this change might not even work if we compare the changes to this PR that's adding Spanish translations: #223

Did you test your changes before committing?

[lukszar]

To be honest I provided just translation strings and didn’t check if multi-language works in the end.

Does it means that translations are not working in WeScan at all?

Does it means that translations are not working in WeScan at all?

Well, they do! But we have to do a bit more than only adding a language file as you can see in this PR.

It's not a lot but we didn't do it in this PR. I haven't find the time to verify that it's actually not working though.

I updated Xcode project for new language. After all tested and it works. I created new PR #224

Hope everything will works this time.
