# Checkout Kit for Swift

Checkout Kit is an open-source [Swift Package library](https://github.com/Shopify/checkout-sheet-kit-swift/blob/main) that allows you to integrate Shopify's checkout in your mobile app. To get started, see our [sample projects](https://github.com/Shopify/checkout-sheet-kit-swift/blob/main/Samples/README.md), or follow the steps below to integrate it into your own project.

***

## What you'll learn

* Integrate Checkout Kit to your project
* Present the checkout through a checkout URL or cart permalink

***

## Requirements

* Swift 5.7+
* iOS SDK 13.0+

***

## Step 1: Install the Checkout Kit as a package dependency

### Package.​swift

## Package.swift

```swift
dependencies: [
  .package(url: "https://github.com/Shopify/checkout-sheet-kit-swift", from: "3")
]
```

### Xcode

1. Open your Xcode project
2. Navigate to `File` > `Add Package Dependencies…`
3. Enter `https://github.com/Shopify/checkout-sheet-kit-swift` into the search box
4. Click `Add Package`

For more details on managing Swift Package dependencies in Xcode, please see [Apple's documentation](https://developer.apple.com/documentation/xcode/adding-package-dependencies-to-your-app).

### Cocoapods

## iOS

```swift
pod "ShopifyCheckoutSheetKit", "~> 3"
```

For more information on CocoaPods, please see their [getting started guide](https://guides.cocoapods.org/using/getting-started.html).

***

## Step 2: Import the library

After adding Checkout Kit as a dependency, you can import the library in your code:

## iOS

```swift
import ShopifyCheckoutSheetKit
```

***

## Step 3: Present the checkout through a checkout URL or cart permalink

To present a checkout to the customer, your app must specify a checkout URL. To get this URL, you can use [Storefront GraphQL API](https://shopify.dev/docs/api/storefront) to build a cart and load its [checkout URL](https://shopify.dev/docs/api/storefront/2023-10/objects/Cart#field-cart-checkouturl). Or, you can provide a [cart permalink](https://shopify.dev/docs/apps/build/checkout/create-cart-permalinks).

When using GraphQL to get a checkout URL, Shopify's [Mobile Buy SDK for iOS](https://github.com/Shopify/mobile-buy-sdk-ios) can simplify the development workflow, as shown in the following code sample:

## iOS

```swift
import Buy


let client = Graph.Client(
  shopDomain: "yourshop.myshopify.com",
  apiKey: "<storefront access token>"
)


let query = Storefront.buildQuery { $0
  .cart(id: "myCartId") { $0
    .checkoutUrl()
  }
}


let task = client.queryGraphWith(query) { response, error in
  let checkoutURL = response?.cart.checkoutUrl
}
task.resume()
```

`checkoutUrl` is a standard web checkout URL that can be opened in any browser.

To present the checkout in your mobile app, call `present` on `ShopifyCheckoutSheetKit`. Pass in the checkout URL, along with other runtime configuration settings, as shown in this code:

## iOS

```swift
import UIKit
import ShopifyCheckoutSheetKit


class MyViewController: UIViewController {
  func presentCheckout() {
    let checkoutURL: URL = // obtained from buyer's cart or cart permalink
    ShopifyCheckoutSheetKit.present(checkout: checkoutURL, from: self, delegate: self)
  }
}
```
