iOS 18.1 Developer Beta 6 Now Available: New Features and Compatible iPhones

Apple has launched iOS 18.1 Developer Beta 6 for eligible iPhone users participating in its beta testing program. This sixth developer beta introduces several new features, including support for Apple Intelligence and an enhanced Siri assistant. Additionally, Apple has released a new version of watchOS 11.1 Developer Beta, which enables Sleep Apnea detection on the Apple Watch Series 10, Series 9, and Watch Ultra 2.

The public release of the iOS 18.1 update is anticipated later this month for eligible iPhones, alongside watchOS 11.1 and macOS Sequoia, which will debut the highly anticipated Apple Intelligence features across its supported ecosystem products.

iOS Developer Beta 6: What’s New

New Apple Intelligence Features

With iOS 18.1 Developer Beta 6, users can now ask Siri for step-by-step guidance on adjusting specific settings on their devices. Additionally, new pop-up notifications will appear, outlining the Apple Intelligence features for each app upon first launch.

Sleep Apnea Detection

The newly introduced Sleep Apnea detection feature, announced with the Apple Watch Series 10, is also available in iOS 18.1 Developer Beta 6. Users running the latest iOS beta on their iPhones can activate this feature on their paired Apple Watch Series 10, Series 9, and Watch Ultra 2. This feature leverages the Apple Watch’s accelerometer to detect breathing irregularities during sleep and analyses data every 30 days, notifying users if it identifies consistent signs of moderate to severe sleep apnea.

Other Changes

Beyond new features, Apple has revamped icons and user interface elements across the board. Grouped notifications for specific apps now indicate the number of merged notifications, and new toggles have been added to the Control Center, including options for the Measure and Level tools from the Measure app.
