Protocol-Oriented Programming in Swift

Speaker: David Abrahams. (Tech lead for Swift standard library)

• "Crusty" is an old-school programmer who doesn't trust IDE's, debuggers, programming fads. He's cynical, grumpy.

• OOP has been around since the 1970's. It's not actually new.

• Classes are Awesome

  • Encapsulation
  • Access control

import Foundation

extension Array {
    
    func zipmap(key key: String, value: String, container: [AnyObject]) -> [[String:AnyObject]] {
        var result = [[String:AnyObject]]()
        let count = min(self.count, container.count)
        for i in 0..<count {
            var mapping = [String:AnyObject]()
            let k = self[i] as! String
