The document summarizes the key points from a Brooklyn Swift Developers Meetup. It discusses the presenter's early excited reactions to Swift being announced at WWDC 2014. The meetup then covered an introduction to Swift, comparing it to Objective-C by highlighting features like namespaces, type safety, closures and tuples in Swift. It demonstrated Swift in a Playground and answered audience questions. Resources for learning more about Swift were provided at the end.

- 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
