Here's a UIButton subclass that supports the highlighted state animation without using images. It also updates the border color when the view's tint mode changes.

class BorderedButton: UIButton {
    override init(frame: CGRect) {
        super.init(frame: frame)

        layer.borderColor = tintColor.CGColor
        layer.borderWidth = 1
        layer.cornerRadius = 5

        contentEdgeInsets = UIEdgeInsets(top: 5, left: 10, bottom: 5, right: 10)
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("NSCoding not supported")
    }

    override func tintColorDidChange() {
        super.tintColorDidChange()

        layer.borderColor = tintColor.CGColor
    }

    override var highlighted: Bool {
        didSet {
            let fadedColor = tintColor.colorWithAlphaComponent(0.2).CGColor

            if highlighted {
                layer.borderColor = fadedColor
            } else {
                layer.borderColor = tintColor.CGColor

                let animation = CABasicAnimation(keyPath: "borderColor")
                animation.fromValue = fadedColor
                animation.toValue = tintColor.CGColor
                animation.duration = 0.4
                layer.addAnimation(animation, forKey: "")
            }
        }
    }
}

Usage:

let button = BorderedButton(style: .System) //style .System is important
