IOS app icon names still require @2x?

94 Views Asked by At

Do icon names still require @2x and @3x for submission..?

Just about every answer I see still references them, but I just saw a doc that said names can be arbitrary..?

I would suggest, using asset catalogs instead of adding them with drag and drop to the project bundle.

In the asset catalog, you can very easily create an App Icon:

Then you can select what devices and iOS version you would like to support and the list of required images will update automatically, telling you what exactly you need:

This approach also allows you to keep all images one next to each other and it's very convenient.


Edit: In case the it's not using the app icons from the asset catalog, you'll have to select it by selecting your Target->General and changing App Icon Source and Launch Image Source :
