title: Getting the current day of the week in Swift
body: <p>I am trying to get the current day of the week in order to change an image based on what day it is. I am getting an error with my current code: "Bound value in a conditional binding must be of Optional type." I'm pretty new to swift and ios, so I'm not quite sure what to change.</p>
  
  <pre><code>   func getDayOfWeek()-&gt;Int? {
      if let todayDate = NSDate() {
          let myCalendar = NSCalendar(calendarIdentifier: NSGregorianCalendar)
          let myComponents = myCalendar?.components(.WeekdayCalendarUnit, fromDate: todayDate)
          let weekDay = myComponents?.weekday
          return weekDay
      } else {
          return nil
      }
  }
  </code></pre>
