Apple’s upcoming iOS 18 software update may be “the biggest” in the company’s history, according to Bloomberg’s Mark Gurman. iOS 18 is expected to be announced at Apple’s annual WWDC event in June. The news comes a few months after Gurman reported that Apple was hoping for iOS 18 to be its most “ambitious and compelling” update in years. Although the latest report doesn’t detail any specifics, Gurman has previously reported that Apple is planning to launch a newer version of Siri that leverages a new AI system. Apple is also expected to launch new features that improve how both Siri and the Messages app can auto-complete sentences and field questions. Plus, Apple Music is expected to get auto-generated playlists, which is something that Spotify introduced last year.
