I'm pretty confused about the requirements for app icons.
I see this in the Xcode interface for applying app icon sizes:
From what I can tell, these are different sizes for different iPhone screens. I'm not clear as to what 2x and 3x represent. Also, from Apple's guides:
Those sizes don't seem to match up with what Xcode is asking for or suggesting. I've seen other answers regarding this on Stack Overflow but the interface for setting the App Icons is different.
I just want a definitive guide on exactly what should be going on in Xcode in regards to app icons for React Native.
Edit: This question was asked here How to add icons to React Native app
but the interface from back then (Dec 2015) is different from the interface I see now.
Thanks in advanced!
