Upcoming iOS Updates: Siri’s AI Overhaul, Digital Passport, and More

Apple’s iOS ecosystem is poised for significant enhancements with the forthcoming iOS 26.4 update, alongside early insights into iOS 27 and iOS 28. These updates aim to introduce advanced features, refine user experiences, and set the stage for future innovations.

Siri’s AI Overhaul

A major highlight of the iOS 26.4 update is the anticipated transformation of Siri. This overhaul is expected to integrate advanced artificial intelligence capabilities, enabling Siri to perform more complex, multi-step tasks by understanding user context and on-screen content. The revamped Siri is slated to integrate more deeply with user data and on-screen content, allowing it to perform more contextual, multi-step tasks.

Apple is now targeting a spring 2026 launch for this feature, likely coinciding with the iOS 26.4 update.

Digital Passport Integration

Another significant addition in iOS 26.4 is the introduction of a digital U.S. passport within the Apple Wallet app. This feature will allow users to present their digital ID at TSA checkpoints for domestic travel, streamlining the identity verification process. It’s important to note that this digital passport is intended for U.S. domestic travel and age or identity verification in apps and stores, and is not a replacement for physical passports required for international travel.

Enhanced Messaging with RCS Support

The upcoming update is also set to enhance the Messages app by incorporating support for the Rich Communication Services (RCS) Universal Profile 3.0. This upgrade will introduce features such as end-to-end encryption, in-line replies, message editing, and the ability to unsend messages. These enhancements aim to bridge the gap between Apple’s iMessage and the broader RCS standard, facilitating richer messaging experiences across different platforms.

Weather via Satellite

An innovative feature expected in iOS 26.4 is Weather via Satellite, which will enable the Weather app to provide forecast access even outside of Wi-Fi or cellular coverage by utilizing satellite connectivity. This addition is particularly beneficial for users in remote areas or during outdoor activities where traditional network connections are unavailable.

Health App Redesign and Health+ Foundation

Leaked information suggests that iOS 26.4 will introduce a redesigned Health app focusing on a new category layout that groups health data more clearly and reduces clutter. The update also aims to simplify metric logging, making it easier for users to add and review health information. This redesign appears to support Apple’s rumored Health+ subscription, which is expected to introduce an AI-powered health and fitness assistant.

Credit Card Autofill in Third-Party Apps

Apple is testing a system that detects when users enter credit card details inside supported third-party apps. When a card is added, iOS may prompt users to save it directly to iCloud Keychain. Once saved, those cards can be used with Autofill across apps, similar to how Safari handles stored payment details today.

Folder Support in Freeform

Freeform is set to gain a long-requested organization feature. The leaked code shows a full folder system that allows users to group boards and sync them through iCloud, enhancing productivity and organization within the app. ([macobserver.com](https://www.macobserver.com/news/ios-26-4-leaks-offer-early-look-at-ios-27-and-ios-28-features/?utm_source=openai))

Looking Ahead: iOS 27 and iOS 28

While iOS 26.4 brings a host of new features, Apple is already laying the groundwork for future updates. Early indications suggest that iOS 27 and iOS 28 will continue to build upon these enhancements, focusing on deeper AI integration, user personalization, and cross-platform compatibility. As Apple continues to innovate, users can anticipate a more seamless and intelligent iOS experience in the coming years.
