Apple John Gruber has found out that cross-compilers are no longer allowed in iPhone OS 4.0. "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 - a tool that compiles C# and .NET apps to the iPhone. It's unclear what this means for tools like Titanium and PhoneGap, which let developers write JavaScript code that runs in WebKit inside a native iPhone app wrapper. They might be OK."

RE[3]: If it's true...

Referring to Qt vs Gtk vs random widget library?

Actually referring more to the consistency of the user experience end users have when running on Linux.

In Windows it's mostly not so bad, since the vast majority of applications use the native toolset, so most languages produce UI that work and look like all the rest of windows (Java a notable exception, of course).

Presumably it still allows you to code in C/C++ with an abstraction around the Apple-specific stuff, but it does rule out a lot of options...

I think things like GTK et al are specifically excluded. They want you writing to the Apple APIs, not something else that runs on top of those APIs.

An example, if you had a C program written against, say, Win32, then you had a library that presents the Win32 API to your C program, but runs on the iPhone OS, then you'd have, effectively, Windows source code compiling and running on the iPhone, via a compatibility library. Those are the kinds of libraries that they're disallowing.

Other abstractions (A new IMPROVED! NSDictionary!), likely not so much. Easier to use OpenGL, likely not, A full boat portable game kit, perhaps.

They want coders writing code for iPhones, not anything else. That's the gist of this.
