Some iOS users have great app ideas, but maybe they're just not very good at programming. Apple could be seeking to broaden app development opportunities to people without typical developer skills if a patent revealed by AppleInsider means anything.
Apple has already released the iBooks Author software package to help streamline the process of publishing ebooks. Although there are already services that help build iOS apps, nothing would compare to a software package from Apple dedicated to the process. Drawings from the patent application show a variety of graphic interfaces that could be used to make apps.
