Is there any need to use @1x images if app is creating above iPhone 4+ devices?

Question

I am creating my app for only iPhone 5, iPhone 6 and iPhone 6+. I got some info as mentioned below:-

1- Normal device which terms to 1 pixel = 1 point @1x (Older iPhone and iPad devices)

2- Retina device which terms to 4 pixels(2 x 2) = 1 point @2x (iPhone 4+)

3- Retina iPhone6 and iPad which terms to 9 pixels (3 x 3) = 1 point @3x (iPhone6+)

Please clarify that is there any need to add @1x images in Images.xcassets?

Answer 1

For iPad 2 you need 1x resolution pics. So for that situation you need 1x images in your image assets but in case you are not officially supporting iPad and iPhones above 4 then you don't need those. But an iPhone only app runs on iPad too so you need to include the images in 1x resolution. In case you are supporting iOS 10 + only then in that case you don't need 1x images as iPad 2 does not support iOS 10.
