Apple released iOS 27 on September 14, 2026, following its iPhone 18 Pro event. The update is available via Settings → General → Software Update and supports iPhone 11 and newer, with Apple Intelligence features requiring iPhone 15 Pro or later.

The main attraction is Siri AI, a ChatGPT-like assistant with on-screen awareness and personal information access. It includes a dedicated app and can be activated via side button. Currently English-only with daily limits, Siri AI will eventually offer paid expanded access and is unavailable in the EU due to regulatory issues.

Other enhancements include Extend/Reframe tools in Photos, photorealistic image generation in Image Playground, shortcut creation by description, and HomeKit video descriptions. Liquid Glass design receives refinements with adjustable clarity. Performance boosts deliver up to 80% faster AirDrop transfers, 70% quicker photo loading, and 30% faster app launches.
