In Pictures: What the rumour mill expects from iOS...
Apple has been edging toward letting apps communicate directly with each other in iOS. With iOS 6, Apple split off some functions from Springboard, the iPhone app launcher, into Backboard, which now handles a set of hardware events, such as touches, button presses, and accelerometer. The two communicate via the XPC interprocess communications primitives, also used in OS X. There is speculation that Apple may broaden this in iOS 8, opening a general way for apps to talk to each other and share data without opening security vulnerabilities.
