Operations states

[huda_elhady]

first I’m sorry, I’m new to iOS development.
I have just started reading the Concurrency by Tutorial book.
and I just don’t understand this part (in the attached image):
what is the relationship between operation being a class that could have variables and gaining the ability to know what state the operation is in at any given point?

hi Huda! the states isReady, isExecuting etc are class properties (vars)

Thanks audrey, I finally understood it
