A [BigQuery](https://cloud.google.com/bigquery/) client for Swift.

## Installation

Add this to your Package.swift:

```swift

.package(url: "https://github.com/oliveroneill/BigQuerySwift.git", .upToNextMajor(from: "0.0.1")),

```

## Usage

To get an authentication from your service account:

```swift

let provider = BigQueryAuthProvider()

try! provider.getAuthenticationToken { response in

    switch response {

    case .token(let token):

        // Your token to be passed into BigQueryClient

        print(token)

    case .error(_):

        fatalError("Something went wrong.")

    }

}

```

You'll need to copy your credentials file at `$GOOGLE_APPLICATION_CREDENTIALS`

to `credentials.json` in the directory that the binary is run in.

To insert:

```swift

let client = BigQueryClient(

    authenticationToken: "",

    projectID: "",

    datasetID: "",

    tableName: ""

)

try client.insert(rows: rows) { response in

    switch response {

    case .error(let error):

        fatalError("Error: " + error.localizedDescription)

    case .bigQueryResponse(let response):

        checkErrors(response.insertErrors)

    }

}

```

To query:

```swift

let query = "SELECT * FROM users"

try db.query(query) { (r: QueryCallResponse) in

    switch r {

    case .error(let e):

        fatalError("Something went wrong.")

    case .queryResponse(let result):

        guard let result = result.rows else {

            guard let errors = result.errors else {

                fatalError("No errors and no rows.")

            }

            print("BigQuery errors: \(errors)")

            return

        }

        printQueryResult(result)

    }

}

```
