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 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.

The tech giant’s sales of apps and services helped profit grow 7 percent from a year ago, even as the company contended with slumping sales in China.
