Xcode: Vector images from PDF bad quality

Question

for my iOS Swift project I use vectorized pdf files from which Xcode renders the @1x, @2x, @3x images.

When I compare the quality of the images generated from P

Answer 1

The PDF should be saved at 1x resolution, Xcode will take that file and rasterize it generating the @1x, @2x and @3x bitmap versions for you.

In your case 3 PNGs with the following dimensions will be generated from your PDF:

• icon.png (54x40px)
• icon@2x.png (108x80px)
• icon@3x.png (162x120px)

From the screenshot you've posted it doesn't appear that the UIImageView in the cell has a size that matches the icon, therefore you get the blur. It's important to understand that the vector image won't be used as such, but will be always rasterized.

Try to save the PDF with the resolution of the UIImageView (100x82px as per your comment) and check again the result.
