CarKey
It may be a while before we actually see the fruit of this addition, but keen developers have discovered Apple laying the ground for a CarKey framework in iOS 13.4 that would give it the ability to store digital car keys from participating automotive manufacturers.
There’s enough code to suggest that CarKey could be ready to go in iOS 13.4, however, so it’s something that we might actually see going live sooner rather than later so that it’s ready in time for this year’s car models.
