# startMonitoringLocationPushes(completion:)

Starts monitoring for the delivery of Apple Push Notification service (APNs) location pushes, and provides a device-specific token for sending pushes.

## Declaration

```swift
func startMonitoringLocationPushes(completion: (@Sendable (Data?, (any Error)?) -> Void)? = nil)
```

```swift
func startMonitoringLocationPushes() async throws -> Data
```

## Parameters

- `completion`: The completion handler to call after you start monitoring location pushes. The completion handler takes the following parameters:

## Discussion

Discussion important: You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration: func startMonitoringLocationPushes() async throws -> Data For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously. This function requests an Apple Push Notification service (APNs) token that the system uses to launch your Location Push Service Extension and deliver pushes. Devices need an Internet connection to receive the token. Your completion block receives the token if the call succeeds, otherwise it receives error information. If a compatible iPad or iPhone app calls this method when running in visionOS, the method does nothing. To use location push notifications, your app must have the com.apple.developer.location.push entitlement. For more information about implementing location pushes in your app, see Creating a location push service extension.
