问题
I am teaching myself to program using Swift 3, and I am currently learning about booleans. I noticed that if I want to explicitly declare my variable of type bool, I have two options
Bool
or
Boolean
I was wondering why we have these two options if they are the same? Well, are they the same? This is what I'm confused about.
Thanks in advance.
回答1:
Bool is Swift's boolean data type. Boolean hasn't existed since the early days of Swift.
