iPhone users were very excited with the 3D touch feature of iPhone 6s and iPhone 6s Plus. But the same feature was not available on iPad Pro. Developers created an iOS 9 jailbreak that hacks the Apple Pencil and brings 3D Touch to Apple’s tablet.
Apple didn’t include pressure sensor on the iPad Pro’s display. The 3D touch feature were only incorporated in iPhone 6s and 6s Plus. Apple’s high tech sensor made this hack possible. To give 3D Touch, Sood toiled to hacked the Apple Pencil pressure data to parts of iOS which drives the 3D Touch engine. After certain pressure are met the 3D features are activated which were not supported on iPad.
Apple has not yet planned to introduce 3D touch feature in iPad soon but if you are eager to try it on your iPad Pro for iOS app development go for the hack code on Github.
