title: Can't initialize a struct with a default value
body: <pre><code>struct Struct1 {
    let myLet = "my let"
    let myLet2: Bool
    let myLet3: String
  }
  
  let s1 = Struct1(myLet2: false, myLet3: "My url123")
  </code></pre>
  
  <p>The error is: <strong>missing argument for parameter <code>myLet</code></strong>. Why is that? It has a default value.</p>
