I downloaded the photoshop app icon template here: https://developer.apple.com/design/resources/
I created an icon with zero transparency. When I export using Generate > Image Assets, the PSD generates PNGs that have slight transparency around the edges. During app submission, icons with transparency are rejected.
Can anyone else confirm?
If you must use it, I believe PS understands iOS better when used w/the DevRocket plug-in.
Otherwise, open that icon in Preview on macOS, then save as .png and try again.
You can fix the PSD file yourself so the generated PNG assets have no transparency. Change the filename extension on all layers in Photoshop to ".png24" and the generated files will have no transparency. The color of that 1 edge pixel will be ever so slightly off but at least they won't be transparent. Apple should fix the PSD file they are providing.
