Working with Images,Most user interfaces consist of text, but text alone can appear plain. That’s why the second most common type of information to display on the screen is images. Images can serve purely for decorative purposes, or they can help the user navigate through a user interface.

Limiting Choices with Pickers,Text Fields are great for letting the user enter any type of information such as names or short answers to questions. The problem is that if the user has the freedom to enter anything, they could accidentally (or on purpose) enter invalid data.

Limiting Choices with Toggles, Steppers, and Sliders,Ideally, you want to limit the user to select only valid options. That keeps the user from entering invalid data such as spelling out a number (such as thirty-seven) instead of typing out the number (37). Three additional ways to restrict the user into selecting only valid data are toggles, steppers, and sliders.

Touch Gestures,Allowing the user to control an app through Buttons, Toggles, or Menus is handy, but all of these controls take up space on the screen. To eliminate the need for extra objects on the user interface, your app can also detect and respond to touch gestures that allow direct manipulation of items displayed on the screen.
