Apple has committed to building a seamless copy-paste experience between iPhones and Windows PCs, using its AccessorySetupKit framework, after Microsoft submitted a request through Apple's EU interoperability request system for developers (Engadget).

Microsoft filed the request in March 2026, asking for a way for an app to get persistent access to the iPhone's clipboard — the temporary storage area that holds whatever you've most recently copied — so it can transfer that content to connected devices. Microsoft specifically asked that the app not have to be open on your screen to work, and that users should not have to approve clipboard access every single time they copy or paste (Engadget; Apple Developer).

In a note dated June 26, Apple responded with a commitment to introduce a new solution allowing users to directly copy and paste items between an iPhone and a Windows PC. Apple said the feature will use AccessorySetupKit, a tool it built for securely pairing accessories — like wireless headphones or fitness trackers — with an iPhone without giving those accessories broad access to the phone's Bluetooth or Wi-Fi. Users will need to grant permission once for each paired device to enable clipboard sharing, after which the transfer should work without repeated prompts (Engadget; Apple Developer).

Apple described the development as a significant engineering effort and said it hopes to complete the work by fall 2027, at which point it would enter beta testing ahead of a wide release in the European Union (Engadget; Apple Developer). It is unclear whether Apple will make the functionality available outside the EU (Engadget).

The request system through which Microsoft filed was launched by Apple to comply with the European Union's Digital Markets Act, a law designed to make large tech companies open up their platforms to competitors. The DMA's interoperability requirement applies to Apple's iOS and iPadOS platforms, according to the European Commission's DMA developer portal (European Commission). Apple's own developer support page on DMA compliance states that, to the extent an effective interoperability solution is feasible and appropriate under the DMA, Apple will subsequently develop the solution for release (Apple Developer).

This is not the first DMA-driven change to the iPhone's feature set in Europe. In January 2024, Apple announced changes to iOS, Safari, and the App Store in the EU to comply with the act (Apple Newsroom). In September 2025, Apple said the DMA was forcing it to make "concerning changes" impacting many parts of EU users' experience (Apple Newsroom). More recently, Apple said it will not be able to ship Siri AI in the EU with the release of iOS 27 and iPadOS 27 due to the DMA (Apple Newsroom).

Apple's existing Universal Clipboard feature already allows copy and paste between Apple devices, but only within the company's own ecosystem and within roughly 30 feet (10 meters) (Apple Support). The iPhone Mirroring feature, available in the EU, lets users see and interact with their iPhone from a Mac, including checking notifications and dragging content between devices (Apple Newsroom). Neither feature extends to Windows.

The choice of AccessorySetupKit is notable from an architecture standpoint. The framework was designed to let apps discover and pair with accessories while keeping the pairing flow under iOS system control, limiting the surface area for background access to system resources. Routing clipboard sharing through it, rather than through a more general background-access permission, suggests Apple is attempting to satisfy the persistent-access requirement without granting the kind of always-on clipboard permission that would raise privacy and security concerns. The one-time consent per paired accessory, rather than blanket access, fits that approach.

The timeline also stands out. Even under regulatory pressure, Apple is projecting roughly 15 months from its June 26 commitment to a fall 2027 development completion, with beta testing to follow. That places a production release likely in 2028 at the earliest, and only in the EU. For a feature that Microsoft's Phone Link already approximates on Android, the gap between request and delivery reflects the degree of engineering work Apple says is involved, or at least the pace at which it is willing to prioritize a feature mandated by regulation it has publicly opposed.

The broader pattern here is consistent. Each DMA-mandated interoperability obligation surfaces a tension between the regulatory expectation of timely access and Apple's characterization of the engineering complexity involved. The clipboard request from Microsoft, a company with its own mobile platform history and a vested interest in cross-device experiences via Phone Link, puts that tension on a feature that is simultaneously mundane in concept and intricate in secure implementation.
