title: VIPER design pattern in Swift configuring view
body: <p>I have recently migrated to VIPER and while using this type of architecture came up with such question:</p>
  <p>For instance, I have in designs long(2000pt height) UI with over 50 interface elements like labels, buttons, views, collections and so on and I need to add round corners and shadows to them.</p>
  <p>Where should I configure its appearance? Should it be in View, or somehow in Presenter?</p>
  <p>So far I have extended UIView to create a method to drop shadow.</p>
  <p>Right now, what I have in View module is:</p>
  <pre><code> override func viewDidLayoutSubviews() {
      doctorsNearCollection.backgroundColor = UIColor(white: 1, alpha: 0)
      newsMayBeInterestedCollection.backgroundColor = UIColor(white: 1, alpha: 0)
      recentSavedNewsCollection.backgroundColor = UIColor(white: 1, alpha: 0)
      setupCharts()
      
      scheduleMetting.dropShadow()
      scheduleMetting.layer.cornerRadius = 5
      
      monthlyPerformaceBackground.dropShadow()
      monthlyPerformaceBackground.layer.cornerRadius = 5
      
      firstMeeting.dropShadow()
      firstMeeting.layer.cornerRadius = 5
      firstMeetingNumber.layer.cornerRadius = self.firstMeetingNumber.frame.size.width / 2
      
      secondMeeting.dropShadow()
      secondMeeting.layer.cornerRadius = 5
      secondMeetingNumber.layer.cornerRadius = self.secondMeetingNumber.frame.size.width / 2
      
      thirdMeeting.dropShadow()
      thirdMeeting.layer.cornerRadius = 5
      thirdMeetingNumber.layer.cornerRadius = self.thirdMeetingNumber.frame.size.width / 2
      
      seeAllMeetings.dropShadow()
      seeAllMeetings.layer.cornerRadius = 5
      
      searchForDoctors.dropShadow()
      searchForDoctors.layer.cornerRadius = 5
      
      seeAllSavedNews.dropShadow()
      seeAllSavedNews.layer.cornerRadius = 5
  }
  </code></pre>
  <p>Is this a good practice?
  I'm interested in setting up commonality among the appearance of views as factored out from other methods.  It seems more or less clear to me.
  Thanks in advance.</p>
