I suspect that Apple will simply reject your app if you use identifierForAdvertising for anything that is not advertising-related (i.e. , if you send the identifierForAdvertising to your own servers even though you're not an advertising network or if you send the identifierForAdvertising in the same request with other data that could potentially identify an individual).
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.
