I wasn’t planning on starting my blog that way. However, circumstances mandate it.
Basically, Apple’s new iPhone Developer Agreement terms added to section 3.3.1 are not just unacceptable, hubristic by pretending to specify which tools we use for the job, and anti-competitive. They’re also completely impossible to enforce, and so utterly ambiguous that no one in his right mind should agree to them.
Read the additions again. They are obviously meant to prohibit “translation layers” such as Flash and other similar technologies. But as written, they could mean anything. For instance, suppose you’re using (or a dependency you’re using uses) a build system that dynamically generates headers depending on configuration and/or platform capabilities. It translates specification files to C code! It’s prohibited! Okay, you may say that it isn’t actually “code” which is generated, just defines and similar configuration. What if you use Lex and Yacc (or substitutes), which take a specification (e.g. a grammar in the case of Yacc) and do generate actual C functions? It’s prohibited! And what if you use various tools and scripts to generate variations of C code as part of your build process, because the C preprocessor is not powerful enough for your needs? To say nothing of having (some of) your code be written in Pascal, Fortran, etc.
It’s worse if you consider that the language of the agreement could be interpreted to mean that libraries that abstract even partially the “Documented APIs”, even if you use them from C/C++/Objective-C, could be prohibited. It’s in a limbo, like usage of an on-device interpreter with “sealed” (i.e. not downloadable, not user-changeable) scripts, which isn’t clearly allowed or prohibited (or rather wasn’t; the new terms clearly forbid it), so few people did it for fear of trying the legal waters. Furthemore, someone could come up with a cross-platform meta-framework with a C++ API (very possible, for instance Bada has C++ APIs), and given the intent behind this change it could be something Apple would want to block as well; I’m loathe to use the “Apple may do this in the future, we must block them now” argument, but I’m not doing so, it’s something they could try to do with an interpretation of the current language of the agreement (who’s to say the meta-framework isn’t a “compatibility layer”?).
It’s not just a matter of how the terms are written. Apple is basically trying to mandate how our programs are developed and maintained. What if you have special needs and develop a custom language that compiles down to C (which is then compiled the usual way)? That doesn’t seem very kosher under these terms. What tools we use is our business, not Apple’s; what matters is the output. It’s also dangerously close to mandating what kind of infrastructure software (as opposed to user-facing functionality) is allowed to run on their hardware.
And this disposition is also completely impossible to enforce. If you have a “translation layer” that works entirely by generating C and Objective-C code which is then processed by the SDK tools1, how could anyone or anything tell from the output? False negative and even false positives are going to happen.
You might think you can avoid agreeing to the new terms, keep using the current SDK, and ignore the new APIs and functionality… except one must accept the new agreement to be able to access the provisioning portal past April 22nd; some time after that, the provisioning profiles will expire, and development on a device will be impossible.
So what can we do? I don’t think it makes much sense to boycott development for the plaftorm, or all devices running that platform altogether, because Apple will not realise the loss until it is way too late. So we should let them know these agreement terms are a problem. There is no Radar to dupe, as this is not a matter with a product, instead you should contact them to let them know why you won’t, and possibly can’t, agree to the terms, and ask them to clarify edge cases until these agreement terms become meaningless. For instance, they forgot (I can’t see any other explanation) to list assembler code as one of the mandatory languages, so if you use, or plan to use, assembler as part of your project, contact! The same goes for shader language, so if you use, or plan to use, OpenGL ES 2.0, contact! Oh, and Objective-C++ too! Contact! Games often use a middleware engine, so if you use one, or plan to use one, contact! I’m sure some projects out there use some Pascal, Fortran, Ada or Lisp (why not?), if that’s your case, contact! Using a tool or a fancy build system that generates C code? Contact! Unsure about something? Contact! You can even use your imagination to come up with an edge case that they haven’t anticipated, however no spam please, because we’re not having a temper tantrum, but a legitimate concern about the validity of these new terms.
In closing, I will say that it’s not just a matter of Apple making the rules, and we play by them or not at all. Here Apple has reached the point of hubris, and they must be brought back down to Earth. If they are afraid that iPhone development is becoming more popular because of the installed base than because of the Cocoa Touch framework, and that developers are going to sidestep Cocoa Touch (eventually making them lose their network effect), then the answer is to make and keep Cocoa Touch awesome, which is currently the case; the answer is not to mandate its use.
They may even sidestep the Xcode IDE: Xcode is not doing anything magical, just invoking the compiler, resource compiler, code sign utility, etc.↩
