Apple has released the third betas of iOS 18 and iPadOS 18 to developers. This update follows two weeks after the release of the second betas. Developers can access these betas through their device's Settings app under General and Software Update. A significant new feature is the AI-powered Siri, which integrates world knowledge, personal data, and on-screen awareness. Numerous Apple Intelligence features have also been integrated into apps such as Photos, Safari, and Mail. A dedicated Siri app has been introduced to manage conversations. The "Write with Siri" function is now available systemwide for text generation and feedback. Visual Intelligence has moved to the Camera app and includes a new Siri mode. The Liquid Glass interface has been enhanced with a transparency customization slider. Finally, performance improvements aim to make iOS faster, including quicker app launches and AirDrop transfers.
