# WKBackgroundModes

The services a watchOS app provides that require it to continue running in the background.

## Discussion

To add this key to the Information Property List, enable your WatchKit extension’s Background Modes capability in Xcode.

> Important:
> You can only enable one of the extended runtime session modes (`self-care`, `mindfulness`, `physical-therapy`, or `alarm`). However, you can enable both an extended runtime session mode and the `workout-processing` mode. If you set the background modes using Xcode’s Signing & Capabilities tab, Xcode ensures that these values are set properly.
