Apple today released the first Xcode 27.1 beta. The latest version of the tool adds support for iPhone Duo app development.
Available on Apple silicon Macs running macOS 26.6 or later, Xcode 27.1 includes updated SDKs for the iPhone Duo, and a simulator that supports the device's new poses and orientations.
I mean what do they have to hide lol
So they weren't holding back 27.1 to hide some super secret unannounced Duo features like your article said yesterday?
Exactly. In this article ('https://www.macrumors.com/2026/09/16/heres-why-apple-released-ios-27-2-beta/') yesterday, MacRumors said:

They say iOS there but the implication is also Xcode 27.1 Beta since it's a developer beta.
Apple previously announced that the iPhone Duo will ship with iOS 27.1 ('https://www.macrumors.com/2026/09/09/iphone-duo-ios-27-1/'), which means that software version will contain all sorts of references to the device hidden within the code. If an iOS 27.1 beta were to have been released today, it could have spoiled some smaller iPhone Duo details that did not make it into Apple's event.
