Size Classes to distinguish between iPhone 5, 6 and 6 Plus?

Question

I was very happy to learn that Size Classes are backward compatible with iOS 7 (in some cases). Now I'm wondering - is there a way to use Size Classes to distinguish between iPhone 5, 6 and 6 Plus?

No. Quite the opposite actually, size classes are used to abstract the device away. These are the currently used size class:

compact width, compact height: 3.5", 4", 4.7" iPhones in Landscape mode
compact width, regular height: all currently available iPhones in Portrait
regular width, compact height: 5.5" iPhone in Landscape
regular width, regular height: all currently available iPads regardless of orientation

I understand, but if i want to make changes in only my iphone3.5 and keep the layout as same for all others, what must i do? – Underlayer

It's a problem not being able to e.g. have different font sizes and spacings for iPhone5s and iPhone6s. For certain UI layouts these screens are worlds apart. The size classes are too coarse. – Evoke

It is a joke that +3 years later after @JarrodSmith comment, apple still decides that it is fine to keep all iphones in same size class. Its almost as if apple enjoys all the white space most apps have on the bigger phones... – Laufer

You could try testing against the screen height (or width) eg:

//iphone 5
if UIScreen.main.bounds.size.height == 568.0 {
// your code here
}

iphone screen heights are as follows:

iphone 5 = 568.0

iPhone 6/6s/7 = 667.0

iphone 6/7 plus = 736.0

I'd check for UIScreen.main.bounds.size.height and not for the view size – Sophistry
