Apple’s walled garden is finally opening, with iOS 17 slated to support sideloading apps in compliance with EU regulations.

The EU passed the Digital Markets Act (DMA), targeting so-called “gatekeeper” companies, companies that operate an entire “platform” or ecosystem of products. The legislation prevents gatekeepers from preferring their own products and services over those of their competitors.

The DMA has profound implications for Apple. iOS users will be able to install apps from third-party sources, known as sideloading, rather than exclusively via the App Store.

According to Bloomberg, via MacRumors, iOS 17 will be the first release that will support sideloading. Only time will tell what the full impact will be, but it’s safe to say an iOS that allows sideloading will offer a vastly different experience than the one Apple currently provides.
