Apple released TestFlight version 4.4.0, which adds landscape orientation support for iPhones. This update also includes enhanced resizing capabilities when using iPhone Mirroring on Macs running macOS 27 Golden Gate or later. The changes are detailed in the release notes, alongside general stability improvements and bug fixes.
The update to TestFlight, particularly the landscape orientation and improved mirroring, is a step in preparation for Apple's new foldable device, the iPhone Duo. Earlier, macOS 27 Golden Gate introduced resizable iPhone Mirroring, which was seen as an initial move towards supporting such devices. The iPhone Duo event confirmed Apple's efforts to adapt native iOS apps for the device's various display configurations.
The iPhone Duo is scheduled for presale on October 16, with general availability beginning October 23. The device will start at $1,999 in the US and features a 5.4-inch outer display and a 7.6-inch foldable inner display. This new hardware requires software adaptations, which the TestFlight update addresses.
In landscape mode, TestFlight's interface changes from a single-column app list to a two-column layout. The app details screen also utilizes the increased horizontal space by placing App and Developer information panels side-by-side below the 'What to Test', 'Preview', and 'App Description' sections, optimizing the display for wider screens.
