Hello Swift Community,
The review of of “SE-0188: Make stdlib index types Hashable” ran from November 8th to 14th, 2017. This proposal has been accepted.
During the review, the only point of discussion was whether to go one step further and make conformance to Hashable a requirement for all Collection indices. While this would be a source-breaking change, the core team are receptive to this proposal being pitched and discussed as a separate evolution proposal if it covered the handling of the source compatibility issues.
Thanks to everyone who participated in the review.
