What is new in IOS 27?

As of May 29, 2026, there is no public Apple iOS 27 release. If you meant a current or upcoming Apple iPhone OS version, the most relevant major release is iOS 19, with iOS 20 expected to be previewed at WWDC 2026.

If you’re asking what’s new in the latest major iOS releases, the big changes included:

• iOS 18 (2024): Apple Intelligence features, more Home Screen customization, a redesigned Control Center, and RCS messaging support.
• iOS 19 (2025): Continued Apple Intelligence expansion, more context-aware Siri features, and deeper automation improvements.

If you meant a different product or version number, tell me which one and I’ll summarize the new features.
