The company was slow to roll out its Apple Intelligence suite, including a ChatGPT integration, while a long-awaited AI upgrade to Siri has been delayed until next year.
Walker has been the senior director of the iPhone maker's Answers, Information and Knowledge team since April this year. He has been with Apple since 2013, according to his LinkedIn profile.
He is planning to leave Apple next month, the report said. Walker was in charge of Siri until earlier this year, before management of the voice assistant was shifted to software chief Craig Federighi.
Apple did not immediately respond to a Reuters request for comment.
Recently, Apple has seen a slew of its AI executives leave to join Meta Platforms. The list includes Ruoming Pang, Apple's top executive in charge of AI models, according to a Bloomberg report from July.
