Apple’s iOS 8 operating system is now available to download for iPhone and iPad devices, but apps that utilise the much-touted HealthKit app were pulled at the last minute.
Apple unveiled the iOS 8 operating system in June at its Worldwide Developers Conference (WWDC), touting a raft of features, most notably HealthKit and HomeKit.
The HomeKit and HealthKit platforms are designed to tap into the Internet of Things and healthcare markets. HealthKit is similar, with a fitness focus, so apps can be created that allow the phone to gather and store data on a user's activities.
However, Apple had to pull apps designed to integrate with HealthKit. In a widely reported statement the company said a bug issue had caused the problem, and it hoped to have it fixed before October.
"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."
US site Re/Code heard from several health app developers that Apple had informed them of the delay.
Despite the lack of HealthKit apps millions will no doubt rush to download the new update, although many more may be wary after the iOS 7 overhaul – which was a complete revamp of the platform – caused numerous issues.
iPhone 4 owners were particularly affected as their older devices struggled to handle the update. Apple has now effectively ended support for the iPhone 4 by not making the update available to it.
Despite these issues, though, 92 percent of devices worldwide were running iOS 7 at the start of September, according to Apple data.
