I struggle to imagine a team of more than 10 people writing an iOS app with less than 700 files.
Most noobs, such as those who think 700 files is too many because they've only worked on apps they never published, might just cram everything into that one file.
However, there would be various files for components, functions, etc. Code that's single responsibility and easy to test might mean there are lots of files. There might be upload queues, offline functionality, custom code to go beyond what the ios/android SDKs offer, and so on. DTOs, DAOs, etc. various services..
You probably (won't) get the gist but yeah.
