In a note posted on the iOS Dev Center and, most specifically, on the webpage that lists the new features of the upcoming iOS 4.3, Apple is asking developers to update their apps for the iPad 2 to take advantage of the improved hardware performances of the device.
With a new A5 dual-core chip running at 1 Ghz per core, Apple clearly mentions that most operations inside applications will be faster “ouf of the box” but developers can further tune their software with tools like OpenGL Profiler for “greater performance”. Even though Apple hasn’t stated how much RAM went inside the iPad 2, the A5 chip alone should be twice as fast than the A4 in iPad 1 with graphic performances up to 9x faster. Most apps will be generally faster on the iPad 2, but developers can manually update their apps to use the new iPad 2 hardware if they want to.
Developers are also asked to enhance their apps “with new user experiences” thanks to the iPad 2 cameras and gyroscope + accelerometer. While the possible implementations of rear and front-facing cameras are pretty obvious (self portraits and HD video, expect a lot of Photo Booth and iMovie alternatives coming from 3rd party developers), Apple has put the focus on the precision granted by the combination of gyroscope and accelerometer with “6-axis of motion sensing, including user acceleration, full 3D attitude, and rotation rate”.
The iPad 2 will be released on March 11 and it will come with a special version of iOS 4.3 (containing FaceTime and Photo Booth) pre-installed.
