title: Creating a physics body using a texture's alpha channel not working in Xcode 11.1
body: <p>I have a project that uses a sprite's texture to create the physics body. This works in Xcode 10.1. The same code is not working in Xcode 11.1</p>
  
  <p>I opened a project in 11.1 and the physics body is no longer being detected nor is an outline being shown when <code>view.showPhysics</code> is set to true for any of the sprites using a texture to define its physics body. It still works fine when specifying a circle or rectangle shape for a physics body.</p>
  
  <p>This is how you set it up... right from the Apple docs.</p>
  
  <pre class="lang-swift prettyprint-override"><code>let sprite = SKSpriteNode(imageNamed: "Spaceship")
  sprite.physicsBody = SKPhysicsBody(texture: sprite.texture!,
                                     size: sprite.texture!.size())
  </code></pre>
  
  <p>I see no updated info on Apple's site regarding changes in this functionality.</p>
