Swift Only Features

Below are the features introduced in swift and not present in Objective C

• 'repeat while' which is conceptually equal to 'do while' in C/Objective C
• guard statement
• 'Any' (keyword using which arrays dicts can store objects of discrete type)
• 'fallthrough' (using which we can allow implicit fall-through in switch statement which is not default in Swift unlike Objective C)
• 'AnyObject' conceptually equivalent to id in Objective C
