title: Correct Image and Font Scale on different Devices?
body: <p>I have a simple view with a text and an Image. I ran this app on iPhone6Plus and iPhone5. Then I made a screenshot of both and enlarged the iPhone5 screenshot such that it matches the size of the screenshot from iPhone6Plus. Here is the result: </p>
  
  <p><img src="https://i.stack.imgur.com/ebEFe.png" alt="enter image description here"></p>
  
  <p>As you can se the size of the text the size of the image and there positions are not identical but they should be to look the same on different screen sized. </p>
  
  <p>Here is an example of a <a href="https://github.com/JakeLin/SwiftWeather" rel="noreferrer">weather app</a> running on different screens:</p>
  
  <p><img src="https://i.stack.imgur.com/OT0Y8.jpg" alt="enter image description here"></p>
  
  <p>As you can see the sizes and the positions of text and image are identical. </p>
  
  <p>The image is loaded from asset catalog: </p>
  
  <pre><code>imageView.image = UIImage(named: "shower3")
  self.view.addSubView(imageView)
  imageView.center = self.view.center
  </code></pre>
  
  <p>I have only created a 128x128 image and put it into the @1x version in the asset cataloge.</p>
  
  <p>Let me rephrase this. I run the wether app on iPhone5 make ascreenshot and iPhone6 make a screenshot. Then I resize both screenshots to the same size. Then I see that both fontsize as well as images dimension are exactly equal on both screenshots. This means that on each device font and image must have different dimensions. How can I do that? </p>
  
  <p><strong>How can I achieve that text and image have identical proportions on different screen sizes? How does the <a href="https://github.com/JakeLin/SwiftWeather" rel="noreferrer">Weather App</a> do it?</strong>  </p>
