title: Difference between static enum and static struct
body: <p>Let say that enum or struct are static if they don't store any values in instances. Is there is any difference between static enum and static struct?</p>
  
  <pre><code>enum StaticEnum {
      static var someStaticVar = 0
      static func someStaticFunc() {}
  }
  
  struct StaticStruct {
      static var someStaticVar = 0
      static func someStaticFunc() {}
  }
  </code></pre>
