Check if array contains string

[dillan]

How would you suggest checking to see if an array contains a string. For example:

struct Provider: Codable {
    let items: [String]
    let selectedItems: [String]
}

{% for item in provider.items %}
    {% if provider.selectedItems contains item %}
        {{ item }} contained.
    {% else %}
        {{ item }} not contained.
    {% endif %}
{% endfor %}
