Memory leak found is very hard to track down 😞

Think Valgrind could help here

Well, I uses Mac OS X.

it happens in NSURLSession with a delegate or callback.

If you're using a block based wrapper around NSURLSession it can be easy to create a circular reference. The basic delegate callback mechanism of NSURLSession uses a weak reference and should not create a memory leak.

In your block wrapper if the block contains a reference to this inside of it, it will create a circular reference. You need to make it a weak reference.
