If you want to remove the support for any architecture, for example ARMv7-s in your case, use menu Project - Build Settings -> remove the architecture from "valid architectures".
I've simply toggled "Build Active Architecture Only" to "Yes" in the target's build settings, and it's OK now!
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.
