# configuredWith(configuration:group:body:)

Applies a temporary configuration to the database within the scope of a closure that supports concurrency.

## Declaration

```swift
@discardableResult @preconcurrency func configuredWith<R>(configuration: CKOperation.Configuration? = nil, group: CKOperationGroup? = nil, body: @Sendable (CKDatabase) async throws -> R) async rethrows -> R
```

## Parameters

- `configuration`: An interim configuration to apply to the current database.
- `group`: The group to associate with the methods you execute in the closure. Specifying a group helps the system prioritize those method calls, and helps you identify the calls in the server logs in CloudKit Console. For more information, see doc://com.apple.cloudkit/documentation/CloudKit/CKOperationGroup.
- `body`: The closure to execute with the temporarily configured database.

## Discussion

Discussion Use this method to apply a specific configuration to the current database that lasts only for the duration of the trailing closure. For example, you might want to temporarily elevate the quality of service (QoS) for a group of method calls, or allow one or more expensive method calls to execute only while the device is using WiFi. func fetchRecords(     with ids: [CKRecord.ID] ) async throws -> [CKRecord.ID: Result<CKRecord, any Error>] {

// Get a reference to the user's private database.     let database = CKContainer.default().privateCloudDatabase

// Create a configuration that denies cellular access.     let config = CKOperation.Configuration()     config.allowsCellularAccess = false

// Configure the database and execute an expensive fetch.     return try await database.configuredWith(configuration: config) { db in         try await db.records(for: ids)     } }
