Do I have to follow iOS Data storage guidelines even when iCloud is not enabled for my app?

Yes. It's because everything in the user directory, with the exception of tmp and Library/cache directories, is backed up by default and Apple doesn't want content that is easily regenerated/re-downloaded to be copied into the cloud.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
