Что гугл говорит по поводу этой ошибки?

I find very old info. My friend say this not work on new xcode.

Apple developer forum says ;

As you can see; -999 is caused by ErrorCancelled .

This means: another request is made before the previous request is completed.


session property is deinit before completion of async work

But i don’t know which thing doing that. How can i detect this any suggestion?
