Swift


Convenience of a Modern Scripting language with the Performance of Objective-C

Swift vs. Objective-C




Namespaces• Class names scoped to module

(ie. framework)• No more class prefixes



Type Safety• Compiler performs type checks

to find mismatched types• Allows for type inference

var heyStr = “Hey”



Closures• Nameless function constructed

as another function's argument• Equivalent to Blocks

numbers.map({ (number: Int) -> Int in let result = 3 * number return result})



Tuples• Group multiple values to single value• Supports multiple typeslet someTuple = (10, true, “Hello”)// type (Int, Bool, String)let anotherTuple = (arg1: 100, arg2: “Hi”)// anotherTuple.arg1, anotherTuple.arg2
