Size classes are groups of sizes. Apple sees iOS device sizes as compact or regular. A device may have a compact width or height, or a regular width or height. These attributes change depending on orientation. See how to use these classes to develop bette
- [Teacher] Apple groups devices into having…either a regular width or a compact width…and a regular height or a compact height.…So these are called size classes.…You can see which devices and which orientations…fall into which size classes directly in Xcode.…At the bottom of the screen in Interface Filter,…I want to point you to where it says View As, then will…say the name of the device and then some parentheses.…In the parentheses, you'll see w,…and then a letter, an h, then a letter.…
Of course w is for width and h is for height.…The C stands for compact, and if you're…seeing an R, that stands for regular.…So an iPhone 4S in landscape orientation…has a compact width and a compact height.…So an iPhone 6S Plus or an iPhone 7 Plus has a…compact width and a regular height in portrait.…In landscape, it has a regular width and a compact height.…It's important to understand…which devices have which attributes.…
The reason why this matters is that Xcode actually…allows you to vary your user interfaces based on a…device's width or height being compact or regular.…

11/18/2016These Xcode tutorials help new developers install Xcode and start writing and editing code. Instructor Todd Perkins shows how to build a brand-new user interface (UI) with buttons and menus in Interface Builder, Xcode's intuitive UI design tool, as well as advanced designs that adapt to screen size, aspect ratio, and orientation changes. He reviews the version control and storyboard features, as well as the basics of schemes and behaviors. Plus, learn how to compile and debug apps, test apps in the iOS Simulator, and send your app to Apple for distribution in the App Store.
