Apple is developing a new API that will let third-party accessories, including Meta's Ray-Ban Meta glasses and Quest headsets, automatically pair across a user's Apple devices the same way AirPods and the Apple Watch do today, according to Apple's EU Interoperability Request page.
The plan responds to a request Meta filed in October 2025 under the EU's Digital Markets Act, asking Apple to let a Meta device, once paired with one iPhone or iPad, automatically become available on a user's other Apple devices without extra prompts. Third-party accessories have never been able to tap into that ability, meaning owning non-Apple hardware alongside an iPhone has always involved more friction. If Apple builds this out, that gap will close, at least for whichever manufacturers get access to the new API.
Apple told Meta on February 4 that it plans to let third-party apps access cryptographic materials that make a pairing completed on one Apple device usable on another, secured by a session key and a one-time, per-accessory user consent. Apple expects to finish development by spring 2027 and ship it "shortly thereafter," which points toward an iOS 27.x update, possibly iOS 27.4, though Apple has not yet confirmed a version.
The feature runs on AccessorySetupKit and Proximity Pairing, infrastructure Apple built to comply with a March 2025 European Commission ruling and which only works in the EU today, the same infrastructure behind the proximity pairing feature already live for EU users. Meta has objected that adopting it would force the company to abandon Core Bluetooth, which it relies on for pairing everywhere outside Europe, and has asked Apple to decouple the two. Apple has declined so far, though it told Meta that support outside the EU "is something we are still considering."
The request remains in phase three as of Apple's most recent update. Meta hasn't yet invoked the DMA's formal dispute resolution process, which would trigger a review by Apple's Interoperability Request Review Board within 30 working days. Until then, Apple's plan proceeds with a spring 2027 rollout tied to AccessorySetupKit, in the EU only.
