I'm not sure about iOS developers' intentions, but the better question is why would you make a filesystem case insensitive. Historically, making filesystems case-insensitive was a mistake.

There are some good discussions on the subject:

To summarize

• It's poorly defined (think unicode).
• Every filesystem does it differently.
• Case-insensitivity should be handled in the UI layer.
• Case-insensitivity forces layering violations upon other code.
• Case-insensitivity is contagious.
• Case-insensitivity can lead to security bugs.
• Case-insensitivity adds complexity and provides no actual benefit.

In my opinion this is a good enough argument to make the filesystem case-sensitive.
