2048 for Swift

swift-2048

A port of iOS-2048 to Apple's new Swift language. The game is present and working, but a number of auxiliary features haven't yet been implemented.

Like the original Objective-C version, swift-2048 does not rely upon SpriteKit. See the description for iOS-2048 for more information.

Instructions

You will need the Xcode 6 Developer Preview to build and run the project. However, it should run under either iOS 7 or iOS 8 (on the simulator).

Tap the button to play the game. Swipe to move the tiles.

Thoughts on Swift

Swift is great. Pattern matching, tuples, and typeclasses are amazing. Programming in Swift feels much closer to programming in Scala than in Objective-C. Types are important again.

It's a little disappointing that Apple hasn't provided closure-based callbacks for UIKit controls. Selectors seem pretty hacky in Swift, but they do work.

Still have no idea how to make things private, public, or protected. In Objective-C you could hide internal details away in the .m file. In Swift, everything is exposed by default.

Initializing n-dimensional arrays is painful.

Xcode is as unstable as always. The background compiler/code analyzer kept on crashing and restarting itself. Xcode was functional enough to allow the project to be brought to some state of completion. The debugger is horribly broken though.
