Obj-C, Receiver in message expression is an uninitialized value, analyzer warning?

If you expand the disclosure triangle next to the error (in the error navigator on the left side), it'll show you the exact code path that leads to a situation where the value is not initialized You may think "But, analyzer, really, that can never happen. ". While that may be true, you are creating an assumption in your code that may not hold true in the future due to bug or intentional change.

That increases the fragility of your codebase and will lead to maintenance headaches Fix the code such that it is explicit and remove the assumption.

There is at least one code path that can lead to this line with datStartDate still being uninitialized. That means you have never assigned an object to datStartDate, not even nil.

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.
