If you have been following the iOS 9 news then you would be familiar with the new picture-in-picture feature, which allows users to watch a video or Facetime while simultaneously doing other stuff on their device. Developer Adam Bell found the feature a bit too ‘boring’ so he hacked it to play Doom on it. In the video embedded below you can see him running the game in a small window while using other parts of iOS that includes applications and the springboard. This is something that cannot be done by default.
The developer notes on the video’s description page that he did not use any process injection to achieve this feat nor was his iPad jailbroken. He was able to do it using a public API. This could potentially mean Apple will eventually allow third-party app developers to include the picture-in-picture functionality into their apps, which will make the feature even more useful for the users.
The picture-in-picture feature of iPad along with split-screen view feature is limited to the latest iPad Air 2 only and will be one of the major selling points for the larger 12.9-inch iPad, expected to get released later this year.
iOS 9 will be released for public in the fall while the public beta of the operating system will begin in July.
