What Apple’s new casting shift means
Apple’s move to add third-party casting protocols like Google Cast to iOS 27 is a platform change that lets iPhone users stream media through non-Apple systems and even set them as the default, weakening AirPlay’s long-standing dominance and opening iPhone media casting to wider device ecosystems. Until now, AirPlay has been the only system-level option on iPhone for beaming video, music, and photos to TVs and speakers. That lock-in is set to loosen as Apple prepares iOS 27 with built-in support for alternative casting frameworks. According to Bloomberg’s Mark Gurman, users will be able to pick between AirPlay and another framework as the default pathway for wireless streaming. For anyone searching for a practical AirPlay alternative or typing “Google Cast iPhone” into a browser, this is the clearest sign yet that Apple’s walled garden is starting to show gaps.
The EU Digital Markets Act and Apple’s reluctant openness
The EU Digital Markets Act (DMA) is the driving force behind this change, as regulators push major platforms to reduce self-preferencing and promote interoperability. Apple has treated the DMA as a headache, pointing to unclear requirements and citing security risks in opening up its systems, but it has already allowed alternative app stores, softened some anti-steering rules, and tolerated emulators on the App Store. Media casting is the latest front. Reports indicate that iOS 27 will introduce third-party casting support mainly to satisfy DMA obligations around fair access to key platform features. Apple has been inconsistent in how it ships such changes, keeping some limited to the EU while letting others spread worldwide. That pattern makes it uncertain whether iOS 27 casting flexibility will remain regional or become a global standard, but the regulatory pressure that created it is clear.
Google Cast on iPhone: a real AirPlay alternative
For users, the standout change is straightforward: Google Cast on iPhone, at the system level, no longer confined to individual apps or workarounds. Once iOS 27 arrives, iPhone media casting should let you pick Google Cast as your default route, alongside AirPlay. This brings iPhones closer to parity with Android devices that already use Cast heavily across TVs, speakers, and streaming sticks. It could also reshape hardware decisions. TV makers currently pay for AirPlay support and must meet Apple’s requirements, but broader iOS 27 casting support reduces the pressure to build AirPlay into every screen. Cheaper Google Cast-compatible sticks and televisions become more attractive for iPhone owners, since they will pair cleanly with iOS. For anyone who wants an AirPlay alternative without switching phones, this is the first major systemic path Apple has offered.
A crack in the walled garden and what comes next
Apple’s support for Google Cast and other protocols is more than a small feature; it is another crack in a carefully controlled ecosystem. For years, AirPlay tied iPhone media casting tightly to Apple TVs, HomePods, and licensed TVs. iOS 27 casting changes break that pattern by giving users an explicit choice of default framework and making non-AirPlay casting first-class. This aligns with broader DMA-driven shifts: alternative app storefronts, sideloading, and new payment routes are all chipping away at platform lock-in. It remains unknown whether Apple will keep expanded casting confined to the EU or roll it out globally for code consistency and to pre-empt similar rules elsewhere. Either way, the effect is the same for covered users: more options, less friction when mixing devices, and a clear signal that regulatory pressure can turn closed ecosystems into more flexible ones.
