After a busy week of sessions, Apple's Worldwide Developer Conference has regularly featured a Thursday evening party in Yerba Buena Gardens. This year Apple invited Bastille to perform.
Developers lined up around the block to gain entry into the Bash, where local restaurants offered a range of small plate food ranging from Indian curry to Mexican mole.
The first beer to run out of stock was San Francisco's own Anchor Steam (although if you knew which drink stand to visit, you could continue finding Anchors all night).
Apple's Craig Federighi (above) took the stage to introduce English rock band Bastille, but as the company's senior vice president of Software Engineering covering both OS X and iOS development, Federighi ended up getting some rock star treatment of his own.
As Bastille took the stage, Federighi appeared at the back corner of the event where a growing line of developers waited for an opportunity to say hi and snap a photo with the lead architect of Apple's software.
As the line grew, Federighi looked up and observed "well, that's quite a line," but spending some time taking photos with fans didn't dent his smile (or his famously big hair), even as the line began stretching down the plaza.
Meanwhile the other rock stars, Dan Smith, Kyle Simmons, Will Farquarson and drummer Chris Wood (wearing a WWDC 2014 jacket, visible from the backstage area below) played a series of their own hits (including "Pompeii," which played before the Keynote and throughout the conference as part of Apple's WWDC playlist) and a few comical covers, including a rendition of TLC's "No Scrubs."
Previous WWDC Bash music acts in recent years have included Vampire Weekend, Neon Trees, Michael Franti and Spearhead and OK Go, who also played in WWDC conference jackets back in 2010.
