title: Try casting Equatable generic to string?
body: <p>I'm building a swift package that accepts a generic type as an input, this cannot change. I need to be able to attempt casting that as a <code>String</code> and if not, I'll just default to something else.</p>
  <pre class="lang-swift prettyprint-override"><code>struct ArrayStepper&lt;T: Equatable&gt;: View {
      @Binding var selected: T
      @Binding var values: Array&lt;T&gt;
      
      var body: some View {
          Text(&quot;\(selected)&quot;)
      } 
  }
  </code></pre>
  <p>The above code will give me this error: <code>No exact matches in call to instance method 'appendInterpolation'</code></p>
