Apple’s new iPhone developer agreement bans the use of Adobe’s Flash-to-iPhone compiler

invisibleSHIELD case for iPadJohn Gruber reports for Daring Fireball, “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.

Gruber reports, “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).

Gruber reports, “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… 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.”

“To be clear, I do not think that Apple is singling out Flash CS5,” Gruber writes. “I do think, though, that Flash CS5’s cross-compiler epitomizes the sort of meta-frameworks Apple is not going to allow. Same goes for MonoTouch… I think this comment at Hacker News from ‘raganwald’ nails it.
