139: ‘How Many Fingers Should This Baby Have?’, With Special Guests Craig Federighi and John Siracusa

Apple senior vice president of software engineering Craig Federighi joins the show for a wide-ranging half-hour discussion about Swift -- Apple's new programming language that just went open source. Next, John Siracusa returns to the show to follow up on Federighi's segment on Swift. Other topics include Apple's new Smart Battery Case for the iPhone 6/6S, and our mutual (and perhaps futile) desire to head into this week's premiere of *Star Wars: The Force Awakens* knowing as few spoilers as possible.
