Apple has issued a revised version of the first iOS 26 developer beta, exclusively for iPhone 15 and iPhone 16 models. The update, available now to registered developers via the Settings app, likely addresses critical bugs, though specific changes have not been detailed.
iOS 26 introduces the new Liquid Glass design, emphasizing transparency across the system and supporting updates across Messages, Phone, Safari, Music, Photos, and Camera apps. This redesign debuted at Apple’s recent keynote event.
While this beta is limited to developers for app testing and adaptation, a public beta program is expected to begin in July. The full release of iOS 26, along with iPadOS 26, macOS 26, watchOS 26, tvOS 26, and visionOS 26, is scheduled for September.
The update supports iPhone 11 and newer, with some advanced features requiring iPhone 15 Pro or iPhone 16 models due to Apple Intelligence capabilities powered by on-device large language models.
Alongside iOS 26, Apple announced iPadOS 26 compatibility with iPad Pro (3rd generation and later), iPad Air (3rd generation and later), and newer models. iPadOS 26 also features the Liquid Glass design and improvements to the menu bar and app windowing.
Apple’s ongoing development roadmap includes long-term plans for the iPhone lineup, with anticipations for the iPhone 17 series already circulating.
