Developers can start to try out Apple’s new betas.

Apple is now on the third round of developer betas for iOS 18, iPadOS 18, tvOS 18, watchOS 11, and visionOS 2. AppleInsider and Apple strongly recommend that users avoid installing test operating systems or other beta or RC software on “mission-critical” or primary devices, as there is the small chance of issues that could result in the loss of data. Testers should instead use secondary or non-essential hardware and ensure they have sufficient backups of their critical data at all times.
