title: How to change LocalizedStringKey to String in SwiftUI
body: <p>I am trying to localize markers shown in my AppleMapView using SwiftUI.</p>
  
  <p>However, MKAnnotation's marker title's type is fixed to <code>String</code>. And I don't want to inherit or create custom class because it is too bothering. </p>
  
  <p>What I need is just <strong>cast LocalizedStringKey to String</strong> to set marker's title. Any help on this? </p>
