Apple Releases iOS 27.3 Beta and iPadOS 27.3 Beta to Developers [Download]

Apple has released the first developer betas of iOS 27.3 and iPadOS 27.3 for testing. Both updates carry build number 24C5037i.

The new betas arrive eight days after the public release of iOS 27.2 and iPadOS 27.2, which brought improvements to Siri AI and contextual suggestions in Messages.

Apple has announced that iOS 27.3 will bring Apple Intelligence to China in December. The initial rollout is limited to iPhone and will not include Siri AI or the other next-generation Apple Intelligence features announced at WWDC 2026.

The beta also brings back the redesigned Health app, including an Insights tab, Health Age, and at-home movement evaluations, with expanded language support.

Developers can download the software from the Apple Developer Center. The updates are also available over the air via Settings > General > Software Update when Developer Beta is selected under Beta Updates.
