It seems that this question has largely been answered, but to circle back to the original post, here is (IMHO) a relatively succinct translation in Swift. The key is that you can chain lazy properties. Note that I used both a class function and a closure - either is fine.

import Swift

println("begin")

class ClassWithLazyProperties {

    lazy var entries:[String] = ClassWithLazyProperties.loadStuff()
    lazy var entriesByNumber:Dictionary = {

        var d = Dictionary()
        for i in 0.. [String] {
        return ["Acai", "Apples", "Apricots", "Avocado", "Ackee", "Bananas", "Bilberries"]
    }

}

let c = ClassWithLazyProperties()
c.entriesByNumber
    // 0: "Acai", 1: "Apples", 2: "Apricots", 3: "Avocado", 4: "Ackee", 5: "Bananas", 6: "Bilberries"]


println("end")
