iOS Question Updating from ITunes

[MikeH]

If a user updates my app from iTunes, do the files in DirDocuments, (which is where I put the settings files etc), remain or are they wiped?

I think they will remain.
So far I have no losses registered.

 

[MikeH]

Thanks. They should remain, but I need to know for sure before I upload an update.

 

[Erel]

They will remain.
