Xcode 8 import pdf (vector) intro image assets not working well
<p>I drag pdf intro image assets (universal) and building Xcode. </p>

<p>There is no generated png@2 png@3 . (only Pdf)</p>

<p>I follow this tutorial : 
<a href="https://icons8.com/articles/how-to-use-vectors-in-xcode-7/" rel="nofollow noreferrer">https://icons8.com/articles/how-to-use-vectors-in-xcode-7/</a></p>

<p>When I start app on the device images are so bad quality... </p>

<p><a href="https://i.stack.imgur.com/vrb8B.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vrb8B.png" alt="enter image description here"></a></p>

<p>Xcode 6, 7 working .... 
Maybe PDF file needs optimisation ?!</p>

<p>In research I found "size of svg is not important" but in this case it is (I test it).</p>
