My wife just got an iPhone Pro Max. The cable was a lightning to USB C cable and the charger has a USB C port only.

I’d bet money Apple will move to USB C iPhones at some point. HN would go crazy considering all the negativity around any Apple announcement.

You could just use a lightning to usb-c Apple-cable instead ... No need for an adapter.

I agree with the ridiculousness of it all, but to be fair, there is no such thing as a 2019 iPhone XS. It's a 2018 iPhone XS regardless of when it was purchased or manufactured, although that honestly just makes your situation even more ridiculous.
