WWDC 2026 invitations confirmed

Apple’s media team has started mailing official press passes for the 2026 Worldwide Developers Conference. The keynote is slated for June 3, and the schedule now lists sessions on iOS 27, watchOS 10, and the upcoming visionOS 2 release. For developers, the most immediate impact is the reminder to update Xcode to 15.2 (or later) in order to compile against the new SDKs. Xcode 15.2 ships with the iOS 27 SDK, which raises the minimum deployment target for new projects to iOS 16.0. Existing apps can continue to target iOS 13+, but any use of the new accessibility APIs will require a minimum of iOS 27.

AI‑enhanced accessibility in iOS 27

Apple’s accessibility roadmap for iOS 27 centers on what the company calls Apple Intelligence. Two headline features are:

1. Live Voice‑Control for Wheelchairs – The system can interpret eye‑gaze and head‑tilt data from the iPhone’s TrueDepth camera and translate it into wheelchair navigation commands. The API lives under UIAccessibilityWheelchairControl and exposes a WCCommand object that developers can feed into third‑party hardware SDKs. Apple provides a sample project on its developer portal that demonstrates Bluetooth Low Energy (BLE) pairing and command streaming.
2. Contextual Image Descriptions – Using the on‑device generative model introduced in iOS 26, the new UIImageAccessibilityDescriptionProvider can generate concise, localized alt‑text for any image view. The provider runs entirely on the device, respecting user privacy while still delivering high‑quality descriptions.

Both features require iOS 27 or later and depend on the Vision framework version 4.0, which adds VNDetectEyeGazeRequest. Developers targeting older OS versions must fall back to the classic UIAccessibilityCustomAction path, so a runtime check such as if #available(iOS 27, *) { … } is essential.

Siri becomes a beta‑labeled standalone app

Mark Gurman’s latest report confirms that Apple will ship a new Siri app for iOS 27, labeled as a beta from day one. The app will live at com.apple.siri.beta and will include:

• Auto‑deleting chat history – Users can enable a setting that removes conversation data after 24 hours. The setting is exposed via SiriSettings.shared.autoDeleteEnabled.
• On‑device inference – Most natural‑language processing runs locally, reducing reliance on cloud endpoints. Developers can still call the SiriKit intents, but the response latency is expected to drop by roughly 30 %.
• Beta badge – The App Store entry will display the familiar beta label, signalling that APIs may change before the final release.

For developers, the shift means two practical steps:

1. Update your app’s Info.plist to include the new SiriUsageDescription key that explains the auto‑delete feature. Failure to do so will cause the app to be rejected during App Store review.
2. Test against the beta SDK – Apple is providing a pre‑release version of the Siri framework in Xcode 15.2 beta 3. It introduces the SiriChatSession class, which replaces the older INInteraction for conversational flows. Existing code that relies on INSendMessageIntent will still compile, but Apple recommends migrating to the new class to take advantage of on‑device processing.

Migration checklist for developers

Area	What changes in iOS 27?	Action items
Accessibility	New UIAccessibilityWheelchairControl and UIImageAccessibilityDescriptionProvider	Add runtime checks, integrate Vision 4.0, test with assistive devices
Siri	Standalone beta app, auto‑delete, on‑device inference, new SiriChatSession	Update Info.plist, adopt SiriChatSession, verify privacy prompts
SDK	Minimum deployment target for new features is iOS 27; Xcode 15.2 required	Install Xcode 15.2, set IPHONEOS_DEPLOYMENT_TARGET appropriately
Testing	WWDC 2026 will include a dedicated “Accessibility AI” lab	Register for the lab, run UI tests on devices with TrueDepth cameras

What this means for cross‑platform teams

Developers maintaining both iOS and Android versions should note that the AI‑driven accessibility tools have no direct counterpart on Android yet. If your app offers wheelchair control on iOS, you will need to provide an alternative UI path on Android, perhaps using Google’s Accessibility Service APIs. The new image‑description generator can be approximated with ML Kit on Android, but the on‑device privacy model differs, so you’ll have to document the variance for users.

Preparing for WWDC

The conference agenda lists a deep‑dive session titled “Building AI‑first accessibility experiences” on June 4 at 10 am PT. Register early, bring a device that supports TrueDepth, and plan to test the wheel‑control sample code live. For teams that cannot attend, Apple will publish the session videos on the Apple Developer portal within 24 hours.
