Moved us to xcstrings catalog today. I don't think this is long-term scalable.
In my case, just the migration PR had:
Additions: 427 000 lines
Deletions: 155 000 lines
Each file had ~4 800 lines
So from 4 800 lines per language (about 20) we now have one single file with 425 000 thousand of lines - and yet, it lags when you are opening it. :)
