Swift Notes

:: Swift iOS Version Checking ::

let iOS7 = floor(NSFoundationVersionNumber) <= floor(NSFoundationVersionNumber_iOS_7_1)
let iOS8 = floor(NSFoundationVersionNumber) > floor(NSFoundationVersionNumber_iOS_7_1)

:: Replace Magic Strings with Enumerations in Swift ::

enum SegueIdentifier: String {
	case OtherScreenSegue1 = "otherScreenSegue1"
	case OtherScreenSegue2 = "otherScreenSegue2"
	case OtherScreenSegue3 = "otherScreenSegue3"
}

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {

	if let identifier = SegueIdentifier.fromRaw(segue.identifier) {
		switch identifier {
		case .OtherScreenSegue1:
			println("Going to other screen 1")
		..
		default:
			println("Going somewhere else")
		}
	}
}

:: Print obj Type ::

let typeLongName = _stdlib_getDemangledTypeName(obj)
let tokens = split(typeLongName, { $0 == "." })
if let typeName = tokens.last {
	println("Variable \(obj) is of Type \(typeName).")
}
