Cool, yea let's do this - according to the documentation - Hashable conformance requires Equatable, so you probably only need Hashable.

Cool, I'll delete the explicit Equatable. Thanks!

📲 What
Update the date formatter to conform to
HashableandEquatableby default instead of having custom implementations. This has the effect of also relying on thedateFormatwhen comparing twoDateFormatterConfigobjects.Also add a test that fails without these changes and passes now that the caching is fixed.
🤔 Why
Currently, when the
dateFormatis ignored in comparisons, when we try to parse a different date format, we fetch a cached one expecting a different format, leading to a crash. This happens any time we try to create a formatter for a config that has a different date format but is otherwise identical to a formatter that's already been cached. Specifically, this happens when we show the creator tools deprecation banner and also show credit card expiration dates without killing the app in-between.👀 See
