16. Swift vs. Objective-C Brooklyn Swift Developers Meetup
17. Swift vs. Objective-C Brooklyn Swift Developers Meetup Namespaces • Class names scoped to module (ie. framework) • No more class prefixes
18. Swift vs. Objective-C Brooklyn Swift Developers Meetup Type Safety • Compiler performs type checks to find mismatched types • Allows for type inference var heyStr = “Hey”
19. Swift vs. Objective-C Brooklyn Swift Developers Meetup Closures • Nameless function constructed as another function's argument • Equivalent to Blocks numbers.map({ (number: Int) -> Int in let result = 3 * number return result })
20. Swift vs. Objective-C Brooklyn Swift Developers Meetup Tuples • Group multiple values to single value • Supports multiple types let someTuple = (10, true, “Hello”) // type (Int, Bool, String) let anotherTuple = (arg1: 100, arg2: “Hi”) // anotherTuple.arg1, anotherTuple.arg2
