Tim Cook has dismissed as "bologna" speculation that Apple's iPhone XR is a flop. In an interview with Jim Cramer, Cook said that since Apple started shipping the XR, it's been the most popular iPhone every day. Apple has had a rocky start to 2019 after last week's shock earnings warning. But just hours after the interview, the Nikkei Asian Review reported that Apple is cutting iPhone production by 10% between January and March.
