The legendary Apple design team hasn't had much luck holding onto leadership since Jony Ive left, and with COO Jeff Williams retiring, the leadership role will shift to CEO Tim Cook.

Apple’s chief operating officer plans to hand the role off this month and retire later this year after roughly a decade as the tech giant’s No. 2 under Chief Executive Tim Cook.

Apple CEO Tim Cook is about to take over one of the most significant parts of Apple’s business: its design team. The team currently reports to COO Jeff Williams, but once Williams begins his just-announced retirement “late in the year,” the design team “will then transition to reporting directly to Cook,” Apple says.
