In Objective-C, when a property is lazily instantiated, it is common to need to perform some initial setup of the object that is going to be returned before returning it.

The only way to accomplish this same task in Swift seems to be to use a second property, which is less than ideal.

Example of using a second property:

    @lazy var _heavyView = UIView(frame: CGRectZero)

    var heavyView: UIView {
    get {
        _heavyView.layer.masksToBounds = true
        _heavyView.layer.cornerRadius = 8.0

        return _heavyView
    }
    set {
        _heavyView = newValue
    }
    }

My suggestion is that when declaring an @lazy property, you should be able to define a closure for setting up that property, like this:

    @lazy var heavyView = UIView(frame: CGRectZero) {
        heavyView.layer.masksToBounds = true
        heavyView.layer.cornerRadius = 8.0
    }
