Apple will introduce new versions of iOS and OS X at its annual developer's conference.
Apple Once Again Allowing HealthKit-Capable Apps in iOS App Store
One of the first apps to debut with HealthKit today is FitPort [Direct Link], a replacement for the iOS 8 Health app. The fitness dashboard allows users both to view health stats pulled from Apple's Health database and to enter new data manually. Now that Apple is approving these apps, there should be a deluge of new HealthKit-capable apps appearing in the App Store in the coming days.
Apple planned to fix the HealthKit issue with iOS 8.0.1, but problems with cellular connectivity and Touch ID functionality on iPhone 6 and 6 Plus devices forced Apple to pull the update shortly after release. The company fixed these iOS problems and updated HealthKit in iOS 8.0.2, which was released late Thursday.
