3 Secret iOS 27 Features Coming Before iPhone 18 Pro Launch

Apple plans to launch three additional iOS 27 features by the release of the iPhone 18 Pro, according to Bloomberg reporter Mark Gurman. These updates include a fully customizable Camera app layout, an open API allowing third-party AI assistants to integrate with Siri, and a simplified Modular Ultra watch face for Apple Watch.

Why are some iOS 27 features missing from the initial beta?

Apple omitted several key functionalities from the first iOS 27 developer beta to refine stability and manage regulatory risks. Mark Gurman reports that the customizable Camera app, which allows users to reorganize controls based on preference, was absent from the initial release despite earlier rumors. This delay follows early beta feedback where users criticized the new Siri integration for displacing essential tools like portrait mode.

Pro Tip: If you’re testing the current beta, use the Feedback Assistant app to request specific layout changes for the Camera app. Apple often prioritizes features based on high-volume developer requests before the September public release.

How will the new Siri API change AI integration?

Apple is shifting from case-by-case partnerships to an open extension system for Siri. While the current integration with ChatGPT relies on a specific agreement with OpenAI, the upcoming iOS 27 framework will use a dedicated API. This allows any AI application to integrate with Siri without individual negotiations, according to Gurman.

Apple has already held discussions with Google and Anthropic regarding this framework. This move contrasts with the closed-door approach Apple used in 2024, moving toward a model that mirrors how apps interact with the OS via standard APIs rather than exclusive contracts.

What is delaying the AI rollout?

Gurman identifies four primary reasons for the cautious rollout of these AI extensions:

Apple’s New Siri AI is INSANE (iOS 27 Hands-On)

Regulatory Pressure: Ongoing battles with the European Union over the Digital Markets Act (DMA).
Brand Positioning: The risk that superior third-party models might overshadow “Siri AI” immediately after launch.
Legal Risks: Potential legal challenges from existing partners like OpenAI.
User Experience: Concerns that too many AI options would confuse the average consumer.

Did you know? The DMA (Digital Markets Act) forces “gatekeepers” like Apple to allow more interoperability, which is likely why Apple is pivoting toward an open API for AI assistants to avoid further EU fines.

What changes are coming to the Apple Watch?

A simplified version of the Modular Ultra watch face is in development for watchOS 27. According to Bloomberg, this version retains the signature large clock but removes the second row of complications. This change targets users who want the high-visibility layout of the Ultra without the visual clutter of multiple data points.

This development follows a trend of “decluttering” interfaces across the ecosystem, mirroring the proposed changes to the iPhone Camera app where user-defined priority takes precedence over preset layouts.
