how assign nil object in swift. i'm getting error if assigned directly.
nil cannot used nonoptional constants , variables. if constant or variable in code needs work absence of value under conditions, declare optional value of appropriate type
also importante notice:
swift’s nil not same nil in objective-c. in objective-c, nil pointer nonexistent object. in swift, nil not pointer—it absence of value of type. optionals of type can set nil, not object types
i hope helps you!
