The second review of “SE-0180: String Index Overhaul" ran from June 22nd – 28th, 2017.

The proposal is accepted. There was a lively discussion about it, but in the end everyone seems to agree that this is the right thing to do.

As always, I'd like to thank you for your help in making Swift a better language.
