Плохая новость — Apple, кажется, объявила войну Adobe

New iPhone Developer Agreement Bans the Use of Adobe’s Flash-to-iPhone Compiler

Thursday, 8 April 2010

Prior to today’s release of the iPhone OS 4 SDK, section 3.3.1 of the iPhone Developer Program License Agreement read, in its entirety:

3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs.

In the new version of the iPhone Developer Program License Agreement released by Apple today (and which developers must agree to before downloading the 4.0 SDK beta), section 3.3.1 now reads:

3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited).

My reading of this new language is that cross-compilers, such as the Flash-to-iPhone compiler in Adobe’s upcoming Flash Professional CS5 release, are prohibited. This also bans apps compiled using MonoTouch and Unity3D — tools that compiles C# and .NET apps to the iPhone. It’s unclear what this means for tools like Titanium and PhoneGap, but it sounds to me like they’re on the wrong side of this new rule, and the folks behind Appcelerator already realize they might be out of bounds.

There was no mention of this change during the announcement event today, but the language in the agreement doesn’t leave much wiggle room. It could hardly be more clear if they singled out Flash CS5 by name. (Wonder what Adobe does now? CS5 is thiscloseto release and the iPhone compiler is the flagship feature in this version of Flash. They’re pretty much royally fucked.)

I’m not sure how exactly Apple intends to enforce this, but my understanding is that iPhone apps produced by Flash CS5 are easily identifiable as such by inspecting the contents of the app bundle. I’m not sure if there are any “intermediary translation or compatibility layers or tools” which produce app bundles that are indistinguishable from app bundles produced by Xcode and the official SDK.
