Struggling with language switcher for Craft 3

Question

I am using SEOmatic helper class to get localizedUrls which is making life much easier! I would like to only display the localizedurl if the current entry is enable on that site. Below is what I have, has anyone successful done this for craft 3?

{% set currentSite = craft.app.sites.currentSite %}

{% set currentSiteLanguage = currentSite['language'] %}

{% set localizedUrlsArray = seomatic.helper.getLocalizedUrls() %}


{% for localizedUrls in localizedUrlsArray %}

{% if currentSiteLanguage != localizedUrls['language'] %}

    {% if entry is defined %}

        {% if entry.enabledForSite %}

            <a href="{{ localizedUrls['url'] }}"> {{ localizedUrls['language'] }}</a>

        {% endif %}


    {% else %}

        <a href="{{ localizedUrls['url'] }}"> {{ localizedUrls['language'] }}</a>

    {% endif %}

{% endif %}

{% endfor %}

I think I might finally have it working. If someone has a more elegant way to handle the index, tag and category I would love to see it!

        <!-- entry -->
        {% if entry is defined %}

            {% for siteForEntry in entry.getSupportedSites %}

                {% set site = craft.app.getSites.getSiteById(siteForEntry.siteId) %}

                {% if site.id != entry.siteId %}

                    {% set entryForOtherSite = craft.entries.id(entry.id).site(site).one() %}

                    {% if entryForOtherSite is not null %}

                        <li><a href="{{ entryForOtherSite.getUrl() }}">{{ site.name }}</a></li>

                    {% endif %}

                {% endif %}

            {% endfor %}

        <!-- category -->
        {% elseif category is defined %}

            {% set currentSite = craft.app.sites.currentSite %}

            {% set sites = craft.app.sites.getAllSites() %}

            {% for site in sites %}

                {% if site.id != currentSite.id %}

                    <li><a href="{{ site.baseUrl }}blog/category/{{craft.request.getLastSegment()}}">{{ site.name }}</a></li>

                {% endif %}

            {% endfor %}

        <!-- index and tags -->
        {% else %}

            {% set currentSite = craft.app.sites.currentSite %}

            {% set sites = craft.app.sites.getAllSites() %}

            {% for site in sites %}

                {% if site.id != currentSite.id %}

                    <li><a href="{{ site.baseUrl }}{% for segment in craft.request.getSegments() %}{{segment}}/{% endfor %}">{{ site.name }}</a></li>

                {% endif %}

            {% endfor %}

        {% endif %}
