Apple still has three unannounced iOS 27 features in the pipeline: report

Apple concluded its WWDC 2026 keynote this week with a focus on Siri AI and system stability improvements across its platforms. However, according to Bloomberg's Mark Gurman, three significant iOS 27 features remain unannounced and are expected to ship by September 2026.

Simplified Modular Ultra Watch Face

Apple Watch Ultra owners have long favored the Modular Ultra face for its information-dense layout. The company reportedly developed a simplified variant that retains the large clock display but removes the second row of complications. This streamlined version wasn't showcased at WWDC but is anticipated to debut alongside new Apple Watch hardware in September.

For developers building watch complications, this change means evaluating how your widgets will render on a layout with fewer complication slots. The simplified face could affect how users prioritize which complications remain visible.

Siri Third-Party Extensions API

One of iOS 27's most anticipated features involves allowing third-party AI chatbots to integrate directly with Siri. Currently, Apple maintains a partnership with OpenAI that enables ChatGPT functionality within Siri. The new Extensions API would expand this capability to include Anthropic's Claude, Google's Gemini, and other AI services.

The distinction matters for privacy and integration architecture. The existing ChatGPT implementation operates under a formal partnership agreement with specific privacy guarantees. The Extensions API would enable any AI company to integrate through a standard entitlement process, without bespoke agreements.

Apple has reportedly held discussions with OpenAI, Anthropic, and Google regarding this new integration model. From a developer perspective, this opens several considerations:

• Entitlement requirements: Third-party AI services will need to apply for and implement specific entitlements
• Privacy implications: Without partnership-level agreements, data handling policies may differ from the current ChatGPT integration
• App Store review: Integrations will likely face scrutiny regarding data collection and user consent

Gurman suggests several reasons for the delayed rollout: potential conflicts with Apple's stance against the EU's Digital Marketing Act, wanting to give Siri AI a clearer spotlight at launch, and avoiding litigation complications with OpenAI.

For iOS developers building AI-powered applications, this API could eventually provide a standardized way to surface your model through Siri voice commands. However, details on the actual integration flow remain sparse until Apple releases documentation.

Customizable Camera App

iOS 27 was expected to introduce a fully customizable Camera application, allowing users to reposition controls according to their preferences. While features like Siri integration within Camera shipped in the initial developer beta, the customization layer did not.

This feature is now expected to arrive with the iPhone 18 Pro launch in September. For photography app developers, this represents both an opportunity and a challenge. Users accustomed to customizing Apple's native Camera may expect similar flexibility in third-party alternatives.

Developer Migration Considerations

With iOS 27 still evolving through beta cycles, developers should monitor several areas:

1. SiriKit updates: Watch for documentation on the Extensions API entitlement process and integration requirements
2. WatchOS complications: Evaluate how simplified watch face layouts affect your complication designs
3. Camera APIs: Any new customization capabilities in the native Camera app may expose additional frameworks for third-party developers

The September release timeline gives developers approximately three months to prepare for these additions. Apple typically releases final SDK updates alongside new hardware launches, so expect Xcode and documentation updates in early September.
