Unlocking the Power of Lock Screen Widgets in iOS 16
With the introduction of Lock Screen widgets in iOS 16, developers can now provide users with valuable, glanceable information from their app directly on the Lock Screen. Powered by the WidgetKit framework, Lock Screen widgets offer a convenient way for users to quickly access important information without having to unlock their device.
The Benefits of Lock Screen Widgets
Lock Screen widgets enhance the user experience by providing direct access to app functionality from the Lock Screen itself. This saves users time and increases overall efficiency. By adding Lock Screen widgets to your app, you can stand out from the competition and increase user engagement and retention rates.
Getting Started with WidgetFamily
In WidgetKit, Apple provides an enumeration that defines a widget’s size and shape. iOS 14 has three cases: systemSmall, systemMedium, and systemLarge. In iPadOS 15, Apple added systemExtraLarge to create widgets for the larger screen. Extending upon the WidgetFamily enum, the WidgetKit team has added three more cases for iOS and iPadOS 16: accessoryRectangular, accessoryInline, and accessoryCircular.
Creating Different Views for Widgets
Each widget size comes with its own set of constraints, so it’s wise to create a separate layout design for each case. For example, the circular case is perfect for showing the amount of profit or loss as a circular progress bar with 0 in the center, while the rectangular case is useful when more detail needs to be provided.
Decorating the Widget Background
By default, the background is an empty view for the widgets. However, to ensure that a Lock Screen widget looks great on any wallpaper, you can add the AccessoryWidgetBackground adaptive background view that provides a standard appearance based on the widget’s environment.
Hiding Private Information in Widgets
Lock Screen widgets are easily accessible from the Lock Screen, but there may be cases where you want to prevent confidential or private information from displaying in the always-on display of the iPhone 14 Pro or Pro Max. You can hide private or confidential information by adding the privacySensitive modifier to a particular view.
Fitting Widget Content to the Lock Screen
When adding content to Lock Screen widgets, the thumb rule is to provide the smallest, most concise data possible. However, sometimes you may still need to adjust the view. You can provide an optional view for smaller screens so that the data will not truncate.
Best Practices for Lock Screen Widgets
To get the most out of Lock Screen widgets, follow these best practices:
- Keep the content concise and easy to read
- Use the AccessoryWidgetBackground to ensure a standard appearance
- Hide private or confidential information using the privacySensitive modifier
- Provide an optional view for smaller screens
By following these guidelines and best practices, you can create effective Lock Screen widgets that enhance the user experience and increase engagement with your app.
