title: TextureAtlas tool not reading Texture atlas - SpriteKit Texture Atlas Generator Error
body: <p>I am trying to make a node with a simple animation, so I created a animation with each individual frame as a .png file, I stuck them all in a folder, and named it stoneanimation2.atlas . </p>
  
  <p>This is the code I tried:</p>
  
  <pre><code>SKTextureAtlas *atlas = [SKTextureAtlas atlasNamed:@"stoneanimation2"];
  
  
      SKTexture *stone2 = [atlas textureNamed:@"stone2.png"];
      SKTexture *stone3 = [atlas textureNamed:@"stone3.png"];
      SKTexture *stone4 = [atlas textureNamed:@"stone4.png"];
      SKTexture *stone5 = [atlas textureNamed:@"stone5.png"];
      SKTexture *stone6 = [atlas textureNamed:@"stone6.png"];
      SKTexture *stone7 = [atlas textureNamed:@"stone7.png"];
      SKTexture *stone8 = [atlas textureNamed:@"stone8.png"];
      SKTexture *stone9 = [atlas textureNamed:@"stone9.png"];
      SKTexture *stone10 = [atlas textureNamed:@"stone10.png"];
      SKTexture *stone11 = [atlas textureNamed:@"stone11.png"];
      SKTexture *stone12 = [atlas textureNamed:@"stone12.png"];
      SKTexture *stone13 = [atlas textureNamed:@"stone13.png"];
      SKTexture *stone14 = [atlas textureNamed:@"stone14.png"];
      SKTexture *stone15 = [atlas textureNamed:@"stone15.png"];
      SKTexture *stone16 = [atlas textureNamed:@"stone16.png"];
      SKTexture *stone17 = [atlas textureNamed:@"stone17.png"];
      SKTexture *stone18 = [atlas textureNamed:@"stone18.png"];
      SKTexture *stone20 = [atlas textureNamed:@"stone20.png"];
      SKTexture *stone21 = [atlas textureNamed:@"stone21.png"];
      SKTexture *stone22 = [atlas textureNamed:@"stone22.png"];
      SKTexture *stone23 = [atlas textureNamed:@"stone23.png"];
      SKTexture *stone24 = [atlas textureNamed:@"stone24.png"];
      SKTexture *stone25 = [atlas textureNamed:@"stone25.png"];
      SKTexture *stone26 = [atlas textureNamed:@"stone26.png"];
      SKTexture *stone27 = [atlas textureNamed:@"stone27.png"];
      SKTexture *stone28 = [atlas textureNamed:@"stone28.png"];
  
      NSArray *atlasTexture = @[stone2,stone3,stone4,stone5,stone6,stone7,stone8,stone9,stone10,stone11,stone12,stone13,stone14,stone15,stone16,stone17,stone18,stone20,stone21,stone22,stone23,stone24,stone25,stone26,stone27,stone28];
  
      stoneAnimation = [SKAction animateWithTextures:atlasTexture timePerFrame:.01];
  </code></pre>
  
  <p>It worked before, when I only had about 10 frames. But I decided to add more, and I think it messed something up with the atlas itself, because Xcode says "SpriteKit Texture Atlas Generator Error" This is the error message:</p>
  
  <pre><code>Command /Applications/Xcode.app/Contents/Developer/Tools/../usr/bin/TextureAtlas failed with exit code 11
  </code></pre>
  
  <p>Every time that I completely make a new atlas, or just rename it, to see if that works, I get the same error. Also, in build settings, I have "Enable Atlas Generator" set to "YES". And I have tried reseting the IOS simulator, and everything I can think of! Please Help!</p>
