Swift 2: UITableViewDataSource protocol extension
I have been playing around with protocol extensions and I have a problem. Maybe what I want to achieve can’t be done. I have this playground: //: Playground - noun: a place where people can play import UIKit protocol ArrayContainer { typealias T var array: [T] { get } } class MyViewController: UIViewController, ArrayContainer, UITableViewDataSource { typealias T = String var array = ["I am", "an A
Swift Protocol Extensions overriding
I'm experimenting with Swift protocol extensions and I found this quite confusing behaviour. Could you help me how to get the result I want? See the comments on the last 4 lines of the code. (You can copy paste it to Xcode7 playground if you want). Thank you!! protocol Color { } extension Color { var color : String { return "Default color" } } protocol RedColor: Color { } extension RedColor { var
Swift protocol extension method dispatch

So Swift 2 is out, and they fixed enums with variable payloads, so the party
Mixins and traits in Swift 2.0
This is a transcription of a talk I gave at the Dutch CocoaHeads meetup in Rotterdam in July, 2015. Some of the code is out-of-date now that we have Swift 3. However, the ideas are still valid. If you paid attention to this year’s WWDC, you’ve probably seen the session on Protocol-Oriented Programming — or at least heard about it. [Lots of nodding heads in the audience.] It’s an interesting sessio
PHP拡張モジュールでクラス定義 - カイハツニッキ(2008-01-31)
