A bug in the HealthKit suite is forcing Apple to remove all apps using the framework from the App Store. The HealtKit enabled apps were supposed to launch with iOS 8 today, but this is postponed indefinitely.
An Apple representative has said that the company is working on a solution to the problem, which is likely to come out in the next couple of weeks.
Apple spokeswoman Trudy Muller made this statement :
"We discovered a bug that prevents us from making HealthKit apps available on iOS 8 today. We're working quickly to have the bug fixed in a software update and have HealthKit apps available by the end of the month." - Apple
