Apple introduced iOS 27 at WWDC 2026, and it is being positioned as a major performance and AI-focused upgrade for iPhones.

Although Apple has not confirmed an exact public release date, the update is expected to roll out in the second half of 2026, most likely around September or October, following the company’s usual iOS release cycle alongside new iPhone models.

What’s New in iOS 27

Smarter Siri with AI upgrades

Siri is receiving a major upgrade powered by advanced AI models, combining Apple’s own systems with third-party AI technology.

Key improvements include:

• More natural and context-aware conversations
