Kirit Modi's answer was exactly what I needed, although I needed to do one thing to make this work. For those that dont download the test project, make sure to implement your delegate methods:

Swift 3:

extension YourViewControllerClass: RSKImageCropViewControllerDelegate {

    func imageCropViewControllerDidCancelCrop(_ controller: RSKImageCropViewController) {
        _ = self.navigationController?.popViewController(animated: true)
    }

    func imageCropViewController(_ controller: RSKImageCropViewController, didCropImage croppedImage: UIImage, usingCropRect cropRect: CGRect) {
        self.avatarImageView.image = croppedImage
        _ = self.navigationController?.popViewController(animated: true)
    }

}

Swift 2:

extension YourViewControllerClass: RSKImageCropViewControllerDelegate {

    func imageCropViewControllerDidCancelCrop(controller: RSKImageCropViewController) {
        self.navigationController?.popViewControllerAnimated(true)
    }

    func imageCropViewController(controller: RSKImageCropViewController, didCropImage croppedImage: UIImage, usingCropRect cropRect: CGRect) {
        self.avatarImageView.image = croppedImage
        self.navigationController?.popViewControllerAnimated(true)
    }

}
