### Describe the Feature Request

Add support for iOS 27 design language across Ionic components. This includes updated styles, transitions, system interactions, new native UI behaviors, and any system-level visual changes introduced in iOS 27. The goal is to ensure Ionic apps continue to feel native and aligned with Apple’s latest design standards.

### Describe the Use Case

Apps built with Ionic targeting iOS should reflect the current system design to maintain a modern, platform-consistent user experience. With iOS 27 introducing changes to gestures, components, or animations, this feature would help developers adopt the latest platform expectations without custom hacks or overrides.
