Mr Fitchett (http://twitter.com/MattFitchett) points out a change in the iPhone 4.0 SDK that bars use of third-party framework layers. The Register has an article on it – iPhone 4.0 SDK bars un-Jobsian code translation. The pertinent bit seems to be this:
“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)”
So we already knew there was no Java on iPhone (my view on this is that it makes apps run too slowly and stops the experience fromm using an iPhone from being as gorgeously fast and slick as it is), but does this have an impact on using something like MonoTouch or other iPhone application frameworks?
