The attendees wouldn't be allowed to use selfie sticks or any other kind of photo monopod within the bounds of either Moscone West or Yerba Buena Gardens.
Though photography using phones or compact cameras is permitted, developers have already been barred from making audio or video recordings of WWDC events, or using professional photo equipment.
During events like the opening keynote, selfie sticks could potentially give attendees un-obstructed shots of the stage, but might also block the views of other audience members and Apple's own camera crews.
"You are not permitted to make audio or audiovisual recordings of WWDC or take professional photographic or video equipment, or wearable recording devices into Moscone West or Yerba Buena Gardens," Apple's information page announced.
"In addition, you may not use selfie sticks or similar monopods within Moscone West or Yerba Buena Gardens," it read.
A number of other major events have already banned selfie sticks over concerns about them obstructing the views of other people.
WWDC 2015 is scheduled for June 8-12 in San Francisco. Apple is expected to showcase iOS 9 and OS X 10.11 at the event.
