# StartDiveIntent

An App Intent that lets people start a dive session when they press the Action button on Apple Watch Ultra.

## Declaration

```swift
protocol StartDiveIntent : SystemIntent
```

## Mentioned in

Responding to the Action button on Apple Watch Ultra

## Overview

Overview To implement the start dive action, create a structure that adopts the StartDiveIntent protocol. struct MyStartDiveIntent: StartDiveIntent {

static var title: LocalizedStringResource = "Starting a dive session."

func perform() async throws -> some IntentResult {         logger.debug("*** Starting a dive session. ***")

await DiveManager.shared.start()         return .result(actionButtonIntent: StartDive())     } } This intent needs a title property that provides a localized description of the action, and a perform() method, which the system calls when it triggers the intent. To read live depth, water pressure, and water temperature data, see Accessing submersion data. important: Before you can access live dive data, your app needs to include an entitlement to access submersion data. For more information, see Express interest in the Submerged Depth and Pressure API. For more information, see Responding to the Action button on Apple Watch Ultra.
