Users can register to qualify for the beta through Apple's Beta Software Program website. Once registered, users can download and install the appropriate beta update in their device settings. However, these new features are currently only available on select devices, including the iPhone 15Pro released last year and the upcoming iPhone 16 and iPhone 16Pro, and will also be supported on iPads and Macs equipped with the M1 chip or newer.
Previously, these features were limited to being available in the developer beta, but it's important to note that the features in the beta aren't all that's available, and Apple is planning to roll out more updates in the future
Apple plans to release the official versions of iOS18.1, iPadOS18.1 and macOS Sequoia15.1 in October. Users can experience these new features when the official versions are released.
