Apple shares rose in after-market trading on Thursday after the company forecast higher sales than Wall Street expected, a sign the company expects iPhone sales to recover as it rolls out artificial intelligence features.

Sales of Apple iPhones dropped at the end of last year, as the tech firm's roll out of new artificial intelligence (AI) features was met with a lukewarm response. Chief executive Tim Cook said the new features helped to drive stronger sales in the countries where they were available, such as the US.

Apple's latest iPhones are flying off the shelves in some markets, and not in others. Apple CEO Tim Cook says this all comes down to where Apple Intelligence is available, and where it isn't.
