use them well.

3. The guidelines from Apple
• The best widgets give users quick updates or
enable very simple tasks.
• Users tend to open the Today view frequently, and
they expect the information they’re interested in to
be instantly available.
• If you want to create an app extension that enables
a multistep task or helps users perform a lengthy
task, such as uploading or downloading content,
the Today extension point is not the right choice.

4. The guidelines from Apple
• Ensure that content always looks up to date
• Respond appropriately to user interactions
• Perform well (in particular, iOS widgets must use
memory wisely or the system may terminate them)

5. iOS Human Interface
Guidelines
• Design an appearance that looks at home in
Notification Center
• Use the default margins and background
appearance provided by Notification Center
• For best results, focus on drawing your content and
not on drawing backgrounds or other materials.

7. • Avoid making users scroll or vertically shift the view
to see all the information in your Today widget.
• Avoid enabling horizontal swiping or dragging,
because it interferes with navigation between
Notification Center areas.

8. • As much as possible, let users perform a task or
open your app with a single tap (note that the
keyboard is not available within a Today widget).
• Optimize performance so that people get useful
information immediately.

9. If appropriate, let people
tap your Today widget to
open your app
