Apple's iOS 18 to Feature Major AI Enhancements and RCS Support

Expected to be announced in June 2024, the update is described as Apple's most 'ambitious and compelling' in years.

iOS 18, Apple's annual iPhone software update for 2024, is described as 'ambitious and compelling' with major new features and design changes planned.
Apple is reportedly working on a wide array of new artificial intelligence features for iOS 18, including a revamped Siri, AI integration in the Messages app, and new AI features for Apple Music.
Apple has announced that RCS support, the successor to SMS and MMS, will be available on iPhone in 2024, potentially as part of iOS 18.
iOS 18 is expected to be announced at WWDC 2024 in June and released to the general public in September.
Apple's plans for iOS 18 may change between now and next June, and some features could be announced at WWDC 2024 but not released until much later via updates such as iOS 18.1 and iOS 18.2.
