A range of delegate methods also allow view controllers to receive notification of size changes and to respond accordingly. At this point we have an image to recognize and a trained model that can examine it. Well, I say "just", but this is actually quite tricky because there are two potential complexities. An app running in portrait mode on an iPhone 6s, for example, would use the compact width and regular height size class whilst the same app running in portrait orientation would use regular width and compact height size class. Implementing multitasking support within an iOS app is essentially a matter of designing layouts that adapt appropriately to the different size classes outlined in the above diagram.
