title: String.CharacterView - how to convert to String
body: <p>I have tried the following:</p>
  
  <pre><code>let str = self.passwordLabel.text?.characters.dropLast()
  let s = String(describing: str)
  </code></pre>
  
  <p>But it give me the following:</p>
  
  <pre><code>"Optional(Swift.String.CharacterView(_core: Swift._StringCore(_baseAddress: Optional(0x0000618000051e10), _countAndFlags: 9223372036854775810, _owner: Optional(Swift._HeapBufferStorage&lt;Swift._StringBufferIVars, Swift.UInt16&gt;)), _coreOffset: 0))"
  </code></pre>
  
  <p>I just wanted to remove the last char from the string?</p>
