Apple Bans Some iPhone Development Tools

Developers are struggling to understand whether anything other than Apple's development tools will be allowed.
Another post, titled "Clause 3.3.1 of the SDK terms should be removed," expresses similar sentiment.

"The change seems pretty clear that Apple is trying to much more dramatically limit the mechanics of development," said Methenitis. "Read literally, I think Titanium, Unity3D, etc. are probably out of bounds and Adobe CS5 certainly is."

Other tools called into question are Ansca Mobile's Corona, Rhomobile's Rhodes, PhoneGap, and MonoTouch.

Adobe appears to be the main target of Apple's ban. Its Creative Suite 5, due to be released shortly, includes with some versions a program called Packager for iPhone, which converts Flash files into iPhone binaries.

Adobe, however, is putting on a brave face. "We are aware of the new SDK language and are looking into it," the company said in a statement. "We continue to develop our Packager for iPhone OS technology, which we plan to debut in Flash CS5."

The company's 10-Q filing with the SEC on Friday takes a less optimistic approach. "[T]o the extent new releases of operating systems or other third-party products, platforms or devices, such as the Apple iPhone or iPad, make it more difficult for our products to perform, and our customers are persuaded to use alternative technologies, our business could be harmed," the company warns.

Other makers of third-party tools have also reassured users of their products.

David Helgason, CEO of Unity Technologies, maker of Unity3D, said in an e-mailed statement, "We have no indication from Apple that things are going to change. We have a great relationship with Apple and will do everything we can to comply with Apple's TOS (also, these are 'beta TOS,' and these easily get changed) so that we can provide uninterrupted service to our more than 120K users."

Walter Luh, CTO of Ansca Mobile offered similar reassurance to Corona developers. "It is true that when you develop your app, you're initially developing in Lua. But when you click 'Build,' you are getting a real bonafide XCode-produced executable binary," he explained in a blog post. "Obviously, I'm leaving some details out (that's our secret sauce) but ultimately your binary is produced by compiling a combination of Objective-C and C++ code. We use XCode to compile and link these binaries to official iPhone Documented API's. It's why we have always required you to install Apple's iPhone SDK."

Luh also stresses that Ansca Mobile remains committed to complying with Apple's requirements.

Jeff Haynie, CEO of Appcelerator, which makes Titanium, offered a more cautious statement. In a blog post he said, "Since iPhone 4.0 is still in beta, both the APIs and the Terms of Service are covered under NDA, so we cannot speak to specifics or Apple's intent with its proposed language. However, these terms are subject to clarification and change by Apple up through its official launch, which looks to be mid-summer."

Adam Blum, CEO of Rhomobile, tried to allay concerns about the new contractual language in a post to a Google Groups forum. "It seems to me directed at the Flash cross-compiler," he said. "The language literally interpreted would ban all use of third party libraries (framework or otherwise) which are quite widespread on the App Store."

Whether Apple plans to take action against its developers remains to be seen. The company may simply be trying to encourage the use of XCode and Objective-C, without any intention of challenging users of other tools. Another possibility is that Apple, having made its platform successful, wishes to move further toward the closed development model of game console makers, one that would exclude hobbyist developers and makers of low-value, cookie-cutter apps. Most of those commenting on the issue seem to believe that Adobe has the most to worry about.

But clarity on this issue is likely to remain elusive until the iPhone 4.0 SDK leaves beta in a few months.
