, regardless of when access is meaningful to the difference between ordinary variables and optional types, ordinary variables only one state, there is value note: Swift's variable and C/OC, C/OC can have no value, is a random value Is the optional type safe? Is that the inventor of the swift, which can be judged by an optional binding, is entirely security-based, and when we use the basic type we do not have to consider whether there is a worth when we use an optional type, we always remember to
