Adobe’s Flash department has curtailed all Flash and AIR development for the iPhone OS platform. In an indirect yet obvious way, Section 3.3.1 of Apple’s new iPhone developers’ agreement binds developers to a promise that whatever they bring to the iPhone will be created exclusively for the iPhone. It effectively bans the use of cross-platform tools or middleware like Adobe Flash, by saying anything Apple approves must be coded in the company’s own Objective-C, or in C or C++. Mike Chambers, company’s product manager for Adobe Integrated Runtime (AIR), found himself sounding the retreat. “We will still be shipping the ability to target the iPhone and iPad in Flash CS5,” Chambers wrote. “However, we are not currently planning any additional investments in that feature.” Adobe won’t stop developers from using the tools the company already baked into its Creative Suite 5, for targeting the iPhone if they so choose, Chambers said. He just warned that if they do so, Apple may make their lives difficult. He said that personally, he’ll devote the attention he would have paid to iPhone to the Android platform instead, inviting fellow Flash developers to follow suit.
