# enableWaterLock()

Disables the Apple Watch touch screen to prevent accidental taps while submerged.

## Declaration

```swift
func enableWaterLock()
```

## Discussion

Discussion The following rules apply when using Water Lock: You must call the enableWaterLock() method from the main thread. You can only enable Water Lock when the app is running in the foreground during an active workout or location session. The app must be running on a supported device (the WKInterfaceDevice object’s waterResistanceRating property must be WKWaterResistanceRating.wr50). Water Lock remains active until the user unlocks it. You can’t programmatically unlock the watch.
