Exporting i18n translations as iOS strings breaks strings format

[agdt3]

Describe the issue

I've created a number of monolingual translations by importing a JSON i18next file. When I attempt to export/download the translations as iOS strings, I get the following format:
key=value
instead of
"key" = "value";

Example:
Initial JSON string:
"profile.edit.leave_modal.cancel": "Leave without saving",

Output iOS String:
profile.edit.leave_modal.cancel=Leave without saving

I already tried

Not sure how to debug this apart from reading the documentation.

Describe the steps you tried to solve the problem yourself.

• I've read and searched the docs and did not find the answer there.
  If you didn’t try already, try to search there what you wrote above.

To Reproduce the issue

Steps to reproduce the behavior:

1. Upload a JSON i18next translation file
2. Download translations as Apple iOS Strings format

Edit: if this is a translation-tools issue, I can post this ticket over there instead.

Expected behavior

My expectation was that the correct iOS strings format was to be exported (unless I'm seriously misunderstanding something about the iOS strings format).
