+# 📲 Drop-in Checkout Example
+
+This example demonstrates how to integrate drop-in checkout into your iOS app.
+
+## Getting Started
+
+To run the example app:
+
+1. Clone the repo:
+
+```sh
+git clone https://github.com/primer-io/checkout-examples-ios.git
+```
+
+2. Change directory into the repo
+
+```sh
+cd "checkout-examples-ios/Drop-in Checkout/SwiftUI"
+```
+
+3. Open the project
+
+```sh
+open "Drop-in Checkout Example.xcodeproj"
+```
+
+4. Run the project from Xcode 🚀
+
+----
+
+This project requires a server to communicate with Primer's API. To get started quickly, we encourage you to use the [companion backend](https://github.com/primer-io/checkout-example-backend).
+
+## Trying it out
+
+This example app allows you to:
+
+- Generate a client token
+- Make a payment with one of your configured payment methods, using drop-in checkout
+
+For card payments, we support several test cards for different cases. You can find these in our docs:
+
+📄 **[Primer Payments Testing](https://primer.io/docs/payments/testing)**
+
+## Understanding the integration
+
+### PrimerDataService
+
+This class contains all the business logic required to interact with the Primer SDK and start making payments.
+
+This class is intended to be a `kitchen sink` that shows the whole integration in one place. You can use it to bootstrap your own integration.
+
+### ExampleApp
+
+This class contains two static properties that are used to auto-fill settings. You can get a head start by providing a client token or a URL for an endpoint serving client tokens directly in the code.
+
+If you don't provide these, you can provide them on the app's start page once it's launched.
+
+### ExampleAppLogger
+
+This is a logger used to print useful messages during app execution.
+
+You can find these logs by filtering on `[Drop-in Checkout Example App]` in the Xcode debug console.
