App Icon Sizes in Xcode's Assets Catalog

Question

Is the 29pt for the iPhone already in Retina display? Meaning would I have to put 29pt or 58pt? For the iPad is the 29pt referring to the non-retina/1x or the retina/2x?

Answer 1

pt is points. In 1x that is pixels. In 2x you need double the pixels. So 29pt is 29 pixels for the 1x image and it needs to be 58 pixels for the 2x version. And now with 3x it would be 87 pixels.
