In March, Apple delayed its upgraded Siri, saying that “it’s going to take us longer than we thought to deliver” the promised features. At WWDC this week, Apple’s SVP of software Craig Federighi and SVP of worldwide marketing Greg Joswiak shared more details about the decision to delay in an interview with The Wall Street Journal’s Joanna Stern. While Apple was showing real software at that show, Siri “didn’t converge in the way, quality-wise, that we needed it to,” Federighi said. Apple wanted it to be “really, really reliable. “When it comes to automating capabilities on devices in a reliable way, no one’s doing it really well right now,” Federighi said.
