Solution 1

There is library on GitHub https://github.com/marmelroy/Localize-Swift which support language switching in your app.

For translation itself i prefer to export XLIFF to Word (docx format), send Word document to translator on Fiverr a then import translations back from Word document to XLIFF file. There is new tool https://129bit.com/home/xliff-to-word-and-back/
