objective c - Reason for declaring a property as (strong, strong) -


i got large chunk of code else have written. first dismissed typo noticed in several other places well.

the essentials other programmer (not sure of "skill level") declared properties as

the compiler not complain wondering if there reason doing or should consider them "typos"?

(the project uses arc)

i see no sense in doing , surprised compiler not complain that.
