title: Localization resource not properly working
body: <p>Xcode is complaining about: &quot;GuestFlowView.swift:18:25: Failed to produce diagnostic for expression; please file a bug report&quot;</p>
  <p>It seems to be linked to the user of <code>LocalizedStringKey</code> or the variable.</p>
  <p>For example, if I replace :</p>
  <pre><code> GuestFlowImageTab(title: title1,
                     desc: desc1,
                     image: &quot;houseprice&quot;)
  </code></pre>
  <p>by</p>
  <pre><code> GuestFlowImageTab(title: &quot;title1&quot;,
                     desc: &quot;desc1&quot;,
                     image: &quot;houseprice&quot;)
  </code></pre>
  <p>I works because the variable name is considered as a String.</p>
  <p>When using <code>LocalizedStringKey</code>, I use a key defined in the <code>Localizable.strings</code> as defined below:</p>
  <p>&quot;GuestFlowPage1Title&quot; = &quot;tyyuu&quot;;
  &quot;GuestFlowPage1Desc&quot; = &quot;nhjkhkj&quot;;</p>
  <p>below my code.</p>
  <pre><code>struct GuestFlowView: View {
      let title1 = LocalizedStringKey(&quot;GuestFlowPage1Title&quot;)
      let desc1 = LocalizedStringKey(&quot;GuestFlowPage1Desc&quot;)
    
      
      var body: some View {
          VStack {
              TabView {
                  GuestFlowImageTab(title: title1,
                                    desc: desc1,
                                    image: &quot;houseprice&quot;)
                  GuestFlowFormTab()
              }
              .tabViewStyle(PageTabViewStyle())
              .indexViewStyle(PageIndexViewStyle(backgroundDisplayMode: .always))
             
          }
      }
  }
  </code></pre>
  <p>Any idea ?</p>
  <p>It seems that my localizable file is not seen.</p>
