Apple on Thursday disclosed its iPhone sales dipped slightly during the holiday-season quarter, signaling a sluggish start to the trendsetting company’s effort to catch up to the rest of Big Tech in the race to bring artificial intelligence to the masses.

Apple shares rose more than 3% in premarket trading on Friday after the company forecast relatively strong sales growth, hinting at a recovery from a dip in iPhone sales 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.
