I am answering my own question. My runloop was waiting on NSInputStream:read when there was no byte to read. So the func was being queued on in runloop source but as the thread is waiting in on socket read nothing was getting executed.
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.
