Apple released a trio of beta software updates Tuesday for its developers: iOS 10 for the iPhone, MacOS Sierra for computers and laptops and WatchOS 3 for the Apple Watch. Updates to these operating systems were announced in June during the company's annual developers conference known as WWDC.

In addition to an overall refreshed interface, iOS 10 features deeper integration with 3D Touch, more details in notifications, and improved user interaction with Apple's digital voice assistant, Siri.

Sierra features auto-unlock with the Apple Watch, better iCloud Drive storage management and desktop integration with Siri.

Finally, WatchOS 3 promises a faster, smoother wearable experience, new watch faces, and a new control center similar to iOS that gives users quick access to settings like airplane mode and do not disturb.

Apple didn't immediately respond to a request for comment.
