Apple has seeded the fourth beta of iOS 26.1 and iPadOS 26.1 to developers for testing. The build number for this beta is 23B5073a.
Previous betas introduced updates like the new Slide to Stop feature for alarms and timers, a toggle for automatic security improvements, and custom workouts in the Fitness app. Apple also adjusted icon and text alignment in Settings, added input gain controls for external microphones on iPad, reintroduced Slide Over multitasking, and refined the Liquid Glass design with subtler lighting effects.
iOS 26 was a massive update for the iPhone, introducing a universal design language called 'Liquid Glass,' an expansion of Apple Intelligence features, and significant upgrades to core apps. You can find a complete list of changes in the official iOS 26 release notes.
The beta of iOS 26.1 is available to members of the Apple Developer Program. A public beta will likely follow in the coming days.
Developers can download the new build from the Apple Developer Center at the link below. Alternatively, you can visit the Settings > General > Software Update page and choose iOS 26 Developer Beta from the Beta Updates row.
