Split-screen for the Apple iPad might not make it to WWDC
Now, there is talk that Apple may not have the split-screen application ready in time for WWDC, which begins on June 2nd and runs through June 6th. Even if the split-screen is on hold, there still might be some mention of it during the developer conference. Apple is believed to be working on the last necessary bits of code to finish it off. At the time of the original story, there was some talk that the feature would be put on hold until iOS 8.1, and based on Thursday's rumor, this could turn out to be true.
Not all Apple iPads are slated to receive this function. According to those familiar with Apple's plans, only the sequel to the Apple iPad Air will eventually end up with the multi-tasking split-screen capability once Apple has it perfected. Earlier rumors had all of Apple's 9.7 inch slates on the receiving end of an update, that included split-screen/multi-tasking capabilities.
