title: UIImageView doesn't always tint template image
body: <p><strong>In the case below, there are two UIImageViews with the same settings and the same template image... But one tints the image, and one does not</strong></p>
  
  <p>I duplicated working <code>UIImageView</code> and placed it instead of the other and it worked. This happened to me multiple times and this solution always worked, but I still wonder what could I have done wrong? Can it be an Xcode bug? Did something similar happen to you? I have Xcode 8.1.</p>
