title: Instance method 'appendInterpolation' requires that 'Decimal' conform to '_FormatSpecifiable' when attempting to use in SwiftUI
body: <pre><code>import Foundation
  import SwiftUI
  
  struct SampleComponent: View {
    @Binding var value: Decimal
  
    var body: some View {
      return Text(&quot;\(value)&quot;)
    }
  }
  </code></pre>
  <p>Gives me the error:</p>
  <blockquote>
  <p>Instance method 'appendInterpolation' requires that 'Decimal' conform to '_FormatSpecifiable'</p>
  </blockquote>
  <p>This works fine in a playground though:</p>
  <pre><code>import Foundation
  
  var d: Decimal = 4.5
  print(&quot;\(d)&quot;)
  </code></pre>
  <p>Any idea what's going on or how to fix it?</p>
