Apple has released the first beta of iOS 18.5 and iPadOS 18.5 for developers, following just two days after iOS 18.4 and iPadOS 18.4 were made available.
The iOS 18.5 update can be downloaded from the Settings app on compatible devices by going to General > Software Update. However, details about the new features included in the update remain unknown at this time.
Some notable news surrounding the upcoming iOS releases includes information on device compatibility and hardware requirements. For example, it appears that the iPhone XR, iPhone XS, and iPhone XS Max will no longer receive support for the A12 Bionic chip when running the latest iOS 19 operating system.
In other news, Apple has released updates to several other software platforms, including watchOS 11.4, AirPods firmware, and macOS Sequoia 15.4. The latter is available for download through System Settings and provides features such as security improvements and performance enhancements.
