Couldn't load a xcode project because it is already opened from another project or workspace?

I had the exact same problem. Quitting the xcode completely and opening it up again worked.

I have close the Xcode completely but IT didn't work. I have killed the procces and It did finally! :-).

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.
