1 A Few iPad Pro Hints
While these aren’t exactly new features, they’re worth mentioning because of what they could entail. Essentially, code hidden within iOS 12.1 contains some significant hints about the upcoming 2018 iPad Pro lineup.
Those hints suggest that the new iPad Pro devices could swap out their Lightning ports for USB-C. That would allow a range of new abilities, including outputting 4K resolution content to external displays — something that’s also been hinted at in Xcode simulation for the new platform.
BONUS. ECG Support?
The Apple Watch Series 4 has one groundbreaking new feature that sets it apart from essentially every other wearable on the market: the ability to take an electrocardiogram, or ECG, reading. But, like eSIM support, the ECG feature won’t become unavailable until Apple enables it in a future software update.
It’s likely that ECG support will be added in an iOS 12.X update. But, at this point, there isn’t any indication within the iOS 12.1 betas that it’s coming in this release. That, of course, could change before the final release of iOS 12.1 — but it’s just as likely to be added in iOS 12.2 or another point update.
