Let's go! 🥳

Looks great!!! 🎉 Just a few questions:
🤔 Could GitHub be configured to treat .strings files as text instead of binary? So that the difference can be seen (like in Root.strings). I know It may be possible using .gitattributes (here one way) but open to other alternatives as well.
❓ Also, are custom fonts going to be set up in a different PR? Saw them missing on the Info.plist files.

@fedemkr Thanks for the tip! .strings files not showing properly in GitHub has been bugging me for much too long, and you pointed me in the right direction for a fix! This is working for this project now, but was a more involved fix than I initially thought it would be! I added an entry in .gitattributes to tell git how to interpret the .strings files, but there was one other step I needed to complete.

This answer on StackOverflow lead me in the right direction. Turns out, Xcode initially created our Root.strings file with the UTF-16 encoding, even though Apple recommends using UTF-8 instead. I converted the file to UTF-8, but was still seeing weird characters when viewing changes with git diff

After some quick googling, I discovered that when I converted the file from UTF-16 to UTF-8, the extra byte for each character (that is used in UTF-16) was not removed as a part of this conversion, and so our file was then filled with NULL characters. I had to open the file in a hex editor to clean up our file by removing all of the null characters.

Now we have a clean file that can be previewed in GitHub! 🥳

I think the plan is to not use the custom fonts in this rewrite, and to exclusively use the default fonts per platform (San Fransisco and its variants for iOS).

LGTM!! 🚀 Thanks for all the improvements!!
