I migrated ~1000 strings in (just) 10 languages to String Catalogs … and now I have a single 85k lines 3MB JSON file, which is too big to be diff'ed using common tools. This is no good, I will stick to localizable.strings for now. Submitted as FB13781798

Objective-C Thanks, I'll take a look at your example.

Unfortunately I don't see anything in your example that fixes the problem. Thanks anyway.
