18 September 2014Apple, via Tim Bradshaw:
“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.”
A lot of iOS features have been pushed back from the main 8.0 launch, more than usual. I’m not sure if this signifies anything untoward, but it’s definitely strange. Apple has prepped HealthKit ads for the iPhone 6 launch … they certainly weren’t expecting last-minute difficulties.
