What iOS 27’s new casting support actually is
Apple’s upcoming iOS 27 update will add system-level support for Google Cast and other third-party casting protocols, letting iPhone users choose non-Apple options instead of relying only on AirPlay. This means you will be able to beam videos, music, and photos from your iPhone or iPad to compatible TVs, streaming sticks, and speakers using alternative standards that were previously locked behind individual apps, if they worked at all. Today, AirPlay is the only casting system built directly into iOS, and it is tightly woven into Apple’s ecosystem of iPhone, iPad, Mac, Apple TV, and licensed AirPlay-ready TVs and speakers. With iOS 27, Apple will still offer AirPlay, but you will see other options appear alongside it at the system level, with the ability to set them as your default casting method.
How the Digital Markets Act forced Apple’s hand
These new AirPlay alternatives in iOS 27 are not arriving because Apple suddenly wants more openness; they are a response to the European Union’s Digital Markets Act. The DMA is designed to limit how large tech “gatekeepers” control access to their platforms, and casting is now part of that fight. According to Bloomberg, Apple is building support for third-party media-casting protocols in iOS 27 specifically to meet DMA requirements. The company has already had to allow alternative app stores, more liberal rules for game emulators, and some sideloading options. At the same time, Apple has complained that DMA rules are vague and has held back certain features from users in Europe while regulators scrutinize its plans. Whether casting changes will stay limited to EU users or spread worldwide is still unknown.
What Google Cast on iPhone changes for everyday users
For everyday users, the arrival of Google Cast on iPhone means more choice and less hardware lock-in. Instead of having to buy an Apple TV box or an AirPlay-licensed television to mirror your screen or send a video to the big display, you could use an inexpensive Google Cast dongle or any Cast-enabled TV you already own. iOS 27 casting settings will reportedly let you pick a default framework, so if your home is filled with Google Cast devices, you can make that the standard option and avoid manual switching every time. This makes mixed-device households far easier to manage: one person can keep using AirPlay with a HomePod, while another relies on Google Cast on the same phone. It turns Google Cast iPhone setups from a workaround into a first-class, system-level feature.
A crack in Apple’s ecosystem control
From a strategic viewpoint, third-party casting on iOS 27 is a notable crack in Apple’s famous walled garden. Until now, tight AirPlay integration helped steer iPhone owners toward Apple TVs, HomePods, and AirPlay-certified televisions, and TV makers paid licensing fees and met hardware requirements to add AirPlay support. If iPhones gain easy, default-level compatibility with Google Cast and other protocols, that advantage weakens. TV brands could skip AirPlay licensing while still appealing to iPhone users, and streaming gadgets that support Google Cast become far more attractive to Apple owners. This is why many observers see iOS 27 casting changes as more than a convenience tweak: third-party casting Apple support hints at a future where iOS has to live alongside rival ecosystems instead of locking users into Apple hardware at every turn.
What’s next for AirPlay alternatives on iOS
One big unanswered question is how far Apple will extend these AirPlay alternatives in iOS. So far, most DMA-driven features, like alternative app stores and some payment changes, are limited to EU users, while others such as emulator support have rolled out globally. Maintaining different iOS behaviors for different regions adds complexity, so Apple may eventually decide it is easier to offer the same third-party casting Apple features everywhere. However, the company has a record of narrow, “malicious compliance” that meets legal requirements while still protecting its business model. For now, iPhone owners should expect iOS 27 casting improvements to start in Europe and watch for signs of a wider expansion. Either way, the era of AirPlay as the only system-level option is ending, and that will reshape how iOS devices interact with the rest of your living room.
