iOS 27 beta ships over 200 documented changes, and the biggest is a rebuilt Siri with world knowledge, covered in the first 15 minutes alone. The Liquid Glass design system gets visible refinements, performance benchmarks are addressed directly, and the camera and Photos app receive advanced editing tools that take up nearly 8 minutes of the walkthrough.
What makes this worth reading in full is the granular, per-app breakdown across 25 categories including Find My, Wallet, Freeform, and Shortcuts, areas that never get headline coverage but consistently affect daily use. Privacy and security changes get their own dedicated segment starting at 42:00, and accessibility updates are catalogued separately rather than buried.
This is a beta, so nothing here is final, but the feature count and the depth of Siri's rebuild suggest iOS 27 is a larger architectural shift than iOS 26 was. The full 85-minute walkthrough by 9to5Mac's Jeff Benjamin is the most complete public inventory of the release available right now.
