Application Development with Swift 2 (Video 9)

This video tutorial explains how to design a universal iOS application with different layouts for various device sizes. It covers the use of size classes, stack views, and layout constraints to tailor the UI for devices like iPhones and iPads. The tutorial demonstrates embedding elements in stack views, adjusting constraints, and testing layouts on different devices.

What are the three size classes available in iOS for structuring layouts?

• Small, Medium, Large

• Narrow, Wide, Full

• Compact, Regular, Any

• Tiny, Standard, Extended

What is the purpose of embedding elements within a stack view?

• To change the color of elements

• To manage layout changes without affecting other elements

• To increase the size of elements

• To add animations to elements

How can you adjust the alignment of a stack view based on size class?

• By adding more elements to the stack view

• By changing the background color

• By using the attributes inspector and selecting the desired alignment

• By resizing the stack view

What is the first step in resolving layout conflicts?

• Removing all constraints

• Changing the background color

• Adding more elements

• Selecting the stack view and adjusting constraints

How can you switch between different views to check alignments?

• By restarting the application

• By resizing the application window

• By changing the device orientation

• By clicking on the view selector
