Regarding what to anticipate from the presentation, it is common knowledge that Apple has been developing generative AI for a while. Additionally, Apple's CEO Tim Cook has discussed the company's aspirations for generative AI on several occasions. In order to accelerate its expansion in the field, the business recently purchased DarwinAI, a startup, and has been hiring for many generative AI jobs.
With so much going on in the generative AI sector, it's reasonable to presume Apple will discuss AI for the first time during the event. However, this is only a guess and should be taken with a grain of salt because Apple has not officially announced anything on the subject.
Aside from that, Apple is likely to release updated iOS 18, iPadOS 18, watchOS upgrades, and the most recent macOS version for its devices.
