Apple has been forced to withdraw apps that make use of its HealthKit SDK due to a bug in its latest iOS 8 operating system.
According to a Financial Times report, Apple said it will take two weeks to fix a problem with its HealthKit SDK, which is aimed at enabling developers to integrate their health and fitness data with the iOS 8 Health app.
In a statement, the iPhone maker said: “We’re working quickly to have the bug fixed in a software update and have HealthKit apps available by the end of the month.”
Since HealthKit was announced at Apple’s Worldwide Developers Conference in June, the likes of Nike, Jawbone and MyFitnessPal have been working to integrate their apps in time for the launch of iOS 8, alongside the new iPhone 6 models.
However, some developers found that their health and fitness products have been removed from Apple’s App Store due to an unspecified issue with HealthKit.
The maker of calorie intake tracking app MyFitnessPal told Financial Times that it is working on a version without the HealthKit integration to get back up in the store as soon as possible.
The health and fitness features of iOS 8 were touted when Apple unveiled the iPhone 6 and iPhone 6 Plus last week.
The new smartphones feature a barometer to calculate how many flights of stairs people have climbed during the day, while the Apple Watch can monitor heart rate and overall activity.
Apple recently changed its privacy rules to ensure the increasing number of health and fitness apps are not hindered by concerns about how developers use personal data.
