Display app-specific data in the complications on the clock face.
- watchOS 2.0+
Use the ClockKit framework to implement a complication interface for your app. Complications are small interface elements that appear on the clock face and provide quick access to frequently used data. Apps provide data in advance of when it is needed and specify how they want the data displayed. The system updates the appearance of your complication at the time you specify.
Because you specify complication data in advance, you use templates to tell the system how you want that data displayed. ClockKit provides templates for each complication size and style that can be displayed on the clock face. Templates let you arrange text and images. There are also templates for displaying completion rings and other types of formatted content.
