Starting a separate thread for USB-C to Lightning cables... I personally have 2 from Baseus (not-certified)... Fast charging doesn't work, but I can sync my data with my MacBook Pro. I have seen reports about Belkin and Griffin's MFi cables, but still can't find a way to purchase them. Anker has also released it's cable.

It's still a rumor BUT something we all look forward to. For all of using presently using an iPhone/iPad with a MacBook... We have no choice but to get a new cable.
