Apple's HealthKit Is Broken Just Hours Before iOS 8 Is Expected To Arrive

Well, this isn't good.

Just hours before it is expected to release its new iOS 8 mobile operating system, Apple is reportedly facing problems with HealthKit, according to MacRumors.

HealthKit is a service that will allow fitness apps to interact and feed information into Apple's new Health app, which will track a user's heart rate, calories burned, and other fitness-related metrics.

The issue is so severe that Apple has even pulled Healthkit-compatible apps from the App Store, according to Carrot developer Brian Mueller.

Apple is still expected to launch iOS 8 to the public in the next few hours, but there's clearly some kinks that still need to be worked out.
