HealthKit and HomeKit iOS 8 issues in beta 1

The HealthKit found in iOS 8 beta 1 right now will change the health industry as we know it and CEO of Mayo Clinic supported this vision in a statement showcased at WWDC 2014. The Mayo Clinic app is one of the first taking advantage of Apple’s new HealthKit.

Following the keynote developers have been downloading the iOS 8 beta 1 and within the release notes there’s a few problems highlighted to devs that they might experience when testing the HealthKit. We’ve listed these known HealthKit problems below.


HealthKit – Known Issues

  • HKCorrelationQuery only returns objects that were saved with correlations. It should return all data entries matching the predicate.
  • Blood pressure readings saved from Health will not have a correlation stored between the systolic and diastolic readings.


Apple also introduced HomeKit during their keynote and revealed how it will turn iPhones into remote controls for smart homes. You’ll be able to put smart devices into groups and control them using Siri, although partnerships start with a few dozen with many more on the way. We did note a few brands like light bulbs by Philips and Honeywell, but a bigger list of brands can be seen above.

There’s also known issues being presented to iOS 8 beta 1 developers for HomeKit, which might get fixed within beta 2, but for now take a look at these current problems below along with one workaround.


HomeKit – Known Issues

  • The “primary” property will not be available in HMService in the future.
  • HomeKit Bluetooth LE support is not enabled.
  • Siri may not immediately recognize HomeKit data changes.
  • Workaround: To trigger an update to Siri, edit other data used by Siri, such as a contact or the name of a Reminders list.
  • Pairing with the Home Kit Accessory Simulator may fail the first time you try. A second pairing attempt should resolve the issue.
  • A bridge accessory only supports a total of 5 services for all bridged accessories.

Are you looking forward to using HealthKit and HomeKit when iOS 8 releases to the public in fall?
