HomeKit was unveiled at the Worldwide Developers Conference last June.
Apple has said that the first HomeKit-enabled smart-home devices will hit the market next month, denying reports that the launch had been extended to August or September.
Apple spokeswoman Trudy Muller said: "HomeKit has been available for just a few months and we already have dozens of partners who have committed to bringing HomeKit accessories to market and we’re looking forward to the first ones coming next month."
HomeKit, which was unveiled at the Worldwide Developers Conference last June, is a framework in iOS 8 for communicating with and controlling connected accessories in a user’s home.
It lets users to discover HomeKit accessories in their home and configure them, as well as create actions to control those devices. Users will also have the option to group actions together and trigger them via Siri.
The company launched the HomeKit hardware certification programme in November 2014.
Apple said for those who are interested in creating a HomeKit-enabled hardware accessory, they should have an MFi licensee to access the resources for manufacturing hardware that integrates HomeKit technology.
