iOS App Thinning - How to implement it depending on screen size?

Per default Apple only seems to allow @3x, @2x and @1x as suffixes for images and app thinning.

@3x resources seem to be reserved for iPhone 6/7 Plus, even though their screen resolution is smaller than the resolution of the largest iPad Pro - which seems to use @2x.

Is there any way to specifically have 5 different folders with data and use one folder per actual device resolution that is out there? Those folders would be for example (and any new or in-between resolution would use the closest folder and scale):

• 568p
• 1136p
• 1334p
• 2048p
• 2732p

Is that possible somehow?

In the Assets in your Xcode project you can click on the + and add a new image set. There you can right click and add iPhone and iPad individually.
