I’m fairly sure it’s possible to make an iPhone app without copying any of Apple’s copyrighted code or using any of their patents.
This sounds wrong, but I was never particularly interested in iOS app development, so take that with a grain of salt.
The GNU GPL prohibits non-GPL software from even dynamically linking to GPL libraries. Assuming that enforcing such a condition is acceptable under relevant copyright law, and that you can’t make an iOS app without linking to any Apple libraries, Apple does have a legal mechanism to enforce this.
French developers may get a pass, with VLC and all.
The vlc thing is about France not recognising patents on algorithms, unless I’m missing something there’s otherwise no law relevant to software licensing

The GPL has an exception for “system libraries” on this regard, but it’s as handwavy as the rest of the license.
The GPL isn’t meant to be a real license, it’s supposed to be a toxic waste bucket that companies don’t want to interact with. This it succeeds at.
