Should be ready for the final review! Thanks @razvanlitianu for helping with this!

[razvanlitianu]

lgtm!

Oops, moving the strings caused a compilation error because the structure change. I think in this case it's ok to keep them side by side, and move them to the deprecation section only when we actually replace them and they are no longer needed.

[gruberb]

I can't merge I believe! I added the changes!

[razvanlitianu]

Build still failing. Can we also move these back?

This swiftlint error looks.... suspicious? 🛑 2383 out of 2383 tests have failed!. Seems like this has nothing to do with my changes?

Also, seems like the IDE I am using is handling " and ' differently. What do you usually use to make sure to get the right ones?

[razvanlitianu]

I just use the default straight quotes from Xcode. If your editor converts them, check the Smart Quotes setting in Xcode or macOS.

Not sure why this fails again...

@gruberb, thanks for your patience. It seems like some systems were malfunctioning. Finally, the checks passed, and I was able to merge the changes.
