Apple will add new interoperability between iPhones (and iPads) and non-Apple devices in two key areas starting with iOS 26.3, in response to Europe's Digital Markets Act. In Europe only, iOS 26.3 will allow third-party devices like smartwatches to receive notifications and react to them. Pairing Bluetooth devices like earbuds will also potentially get easier with Proximity Pairing, where you can simply bring two devices near each other to pair them. These features were previously proprietary to Apple devices like the Apple Watch and AirPods, and, for now, will remain that way in the rest of the world. The features do require work on the part of device makers in order to be supported. Developers can start that work now with beta versions of iOS 26.3, while the features are expected to be "fully available in Europe" in 2026.
